TPS7B6950QDCYRQ1 - 5V 150mA 40V Ultra-Low IQ LDO | TI
The Texas Instruments TPS7B6950QDCYRQ1 is an automotive-grade (AEC-Q100 qualified) high-voltage ultra-low quiescent-current low-dropout (LDO) linear regulator that delivers a fixed 5.0 V output at up to 150 mA from a 4 V to 40 V input range, packaged in a 4-pin SOT-223 (DCY). An LDO (low-dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage is only slightly higher than the desired output. LDOs are a subset of linear regulators, which in turn belong to the broader power management IC family used in nearly every electronic system. Compared to switching regulators, LDOs introduce no switching noise and require only small input/output capacitors, but dissipate the voltage difference as waste heat. The TPS7B6950QDCYRQ1 targets always-on automotive subsystems where low standby current and wide input tolerance are mandatory. Key features include 15 uA typical quiescent current at light loads, integrated short-circuit and overcurrent protection, thermal shutdown, and a wide -40 C to +125 C operating junction temperature range. The SOT-223 (DCY) package exposes the tab as a thermal pad, allowing sustained 150 mA output without an external heatsink at moderate VIN-VOUT conditions. The device is part of TI's TPS7B69xx-Q1 family that also offers 2.5 V (TPS7B6925-Q1) and 3.3 V (TPS7B6933-Q1) fixed-output siblings. The architecture uses a PNP pass transistor topology that delivers low dropout and inherently low quiescent current. An internal bandgap reference sets the 5.0 V rail accuracy to within +/-2% across line, load, and temperature. Internal protective circuitry monitors junction temperature and output current, latching off the device in fault conditions to prevent module damage. Typical applications include automotive body electronics, remote keyless entry receivers, body control modules, instrument clusters, and standby rails for ECUs that must remain alive while the vehicle is parked. The 40 V input rating tolerates load-dump transients on the 12 V automotive bus, simplifying TVS design. When designing with this device, place the input and output capacitors as close as possible to the IC pins to minimize ESL/ESR. For high VIN-VOUT conditions at 150 mA, verify junction temperature rise using the package thermal resistance, since power dissipation equals (VIN - VOUT) x IOUT.

The device is packaged in a 16-pin HTSSOP (PowerPAD) with an exposed thermal pad for high-temperature automotive environments. An LDO (Low-Dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage is very close to the output voltage. It belongs to the broader family of linear regulators (using a pass transistor in its linear region), which itself sits under the umbrella of power management ICs that include DC-DC converters, charge pumps, and battery management ICs. The TPS7B7702-Q1 is a dual-channel LDO with current sense, providing a compact, integrated solution for powering low-noise amplifiers (LNAs) in active antenna modules via a coax cable. Key features include dual 300-mA outputs, independent adjustable output voltages from 1.5 V to 20 V, integrated current-sense outputs for load monitoring, low dropout voltage, and built-in protection (thermal shutdown, overcurrent limit, reverse-battery protection). The 16-pin HTSSOP with PowerPAD provides efficient heat dissipation for the demanding automotive underhood and cabin thermal envelope. The TPS7B7702-Q1 architecture combines a precision bandgap reference, a high-gain error amplifier, and a low-loss sense element per channel to provide accurate regulation with simultaneous current monitoring. Each channel's sense output produces a current proportional to load, allowing an external ADC or comparator to detect open/short coax conditions without dissipating significant power. Typical applications include automotive active antenna power supplies (AM/FM, DAB, GNSS, satellite radio), infotainment head units, and telematic control units requiring clean, regulated, monitored rails. The wide 4.5-40 V input range and 45 V load dump protection support direct connection to the 12 V automotive battery. When designing with this device, place input/output ceramic capacitors close to the pins, solder the PowerPAD to a minimum 1 square inch of copper, and connect each current-sense pin through an external resistor to ground scaled for the downstream ADC's input range.

It belongs to the TPS7B82-Q1 family, designed for always-on off-battery automotive applications where standby power draw must be minimized to preserve battery life. An LDO (low-dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage is close to the output voltage, distinguished from standard regulators by its low headroom requirement. Within the broader taxonomy, this part is a linear regulator (non-switching), which is itself a sub-category of voltage regulators under the power management IC hierarchy. Unlike DC-DC switching converters, an LDO produces no EMI switching noise but dissipates the VIN-VOUT differential as heat, making it ideal for noise-sensitive analog and microcontroller rails. Key features include a 475 mV typical dropout at 200 mA load, 60 dB PSRR at 100 Hz, integrated over-current protection (OCP) and over-temperature protection (OTP), and AEC-Q100 qualification for automotive use. The 14-pin HTSSOP-EP package with an exposed thermal pad provides a low thermal resistance path for sustained 300-mA delivery. The TPS7B8233EPWPRQ1 uses a PNP-pass architecture combined with a precision bandgap reference, enabling wide input operation (3V to 40V) and tight output accuracy across the -40°C to +150°C junction temperature range. The ultra-low IQ architecture ensures minimal battery drain in standby modes required by ISO 7637-2 and OEM always-on specifications. Typical applications include automotive body control modules, infotainment standby rails, instrument cluster MCUs, lighting controllers, and gateway/ECU power domains. The fixed 3.3V output specifically targets microcontrollers, CAN transceivers, and sensor interfaces that require a stable logic rail directly from the 12V battery bus. When designing with this part, place the input and output capacitors close to the IC and ensure the PCB thermal pad is properly soldered with adequate vias for heat extraction. Designers must also budget for worst-case 40V transient operation during load-dump events.

The Texas Instruments TPS7B8333QDCYRQ1 is an automotive-grade, 150-mA, 40-V low-dropout (LDO) linear regulator with a fixed 3.3V output, housed in a 4-pin SOT-223 (DCY) package. It accepts an input voltage range of 3 V to 40 V (42 V transient tolerant), delivers 150 mA of continuous load current, and features an ultra-low 18 µA quiescent current that makes it ideal for always-on automotive subsystems. According to TI's TPS7B83-Q1 product page, the device is AEC-Q100 qualified for automotive applications and supports temperature grade 1 (-40 °C to +125 °C ambient, junction up to +150 °C). An LDO (Low-Dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage approaches the output voltage. As part of the broader power management IC family, an LDO trades efficiency for simplicity and ultra-low noise, replacing a switching converter's external inductor and EMI with a compact, predictable analog control loop. The TPS7B83-Q1 specifically targets automotive rails where cold-crank (input voltage drops) and load-dump transients (input surges) coexist with microamp standby budgets. Key differentiating features include a wide 3 V to 40 V operating input with 42 V transient survival for load-dump, a fixed 3.3 V output (also available in 5 V as TPS7B8350), an ultra-low 18 µA quiescent current for always-on power, and a fast transient response that minimizes output voltage excursion during load steps. The SOT-223 package also exposes a thermal pad to the PCB copper pour, enabling continuous 150-mA output in the -40 °C to +125 °C ambient range. Architecturally, the regulator uses a PNP-Darlington pass element topology combined with an internal precision bandgap reference and a wide-bandwidth error amplifier. This delivers a low dropout voltage (~190 mV typical at 150 mA) and high ripple rejection across the audio band, with current-limit, thermal-shutdown, and reverse-battery protection integrated. The SOT-223 (DCY) package gives a junction-to-ambient thermal resistance around 55 °C/W on a JEDEC-standard 2-oz test board, allowing practical 150-mA operation without a discrete heatsink. Typical applications include automotive body electronics (RKE, mirror modules, lighting), always-on microcontrollers and CAN transceivers powered directly from the 12 V battery rail, infotainment head-unit standby rails, and industrial sensors that must ride through load-dump pulses. The wide input range also makes it well suited for 24 V truck and bus systems with the same 150-mA output requirement. When designing with this device, ensure the input capacitor is placed as close as possible to the IN pin and that the PCB copper area under the thermal tab is maximized; this tab is the primary heat-dissipation path. For always-on loads, the 18 µA quiescent current keeps drain below ~1 mA per day, which is critical for parked-vehicle battery life.

TPS7B8750QDDARQ1 - 500mA 40V AEC-Q100 LDO w/ PG | HSOIC-8
The Texas Instruments TPS7B8750QDDARQ1 is an automotive-grade, 500-mA, 40-V low-dropout (LDO) linear regulator that delivers a fixed 5.0-V output from a 3-V to 40-V input and integrates an open-drain power-good (PG) indicator, all in an 8-pin HSOIC PowerPAD (DDA) package. The TPS7B8750QDDARQ1 is qualified to AEC-Q100 Grade 1, supports ambient operation from -40 C to +150 C, and is targeted directly at automotive ECUs that must ride out 12-V/24-V battery transients. According to the TI TPS7B87-Q1 datasheet, the part shares a family platform with the TPS7B86xx-Q1 5-V fixed 500-mA siblings, the principal variation being the PG-asserted threshold window and output voltage options. An LDO (Low-Dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage is very close to the output voltage. LDOs sit within the broader hierarchy of linear regulators, which themselves are a category of voltage regulator ICs inside the wider power management IC (PMIC) semiconductor family. Compared to switching converters, LDOs trade conversion efficiency for ultra-low output noise and simple peripheral requirements, typically needing only input and output ceramic capacitors. The "low-dropout" descriptor refers to the small VIN-to-VOUT differential required to maintain regulation, often below a few hundred millivolts at full current. This makes LDOs ideal for post-regulating the output of a switching converter or for cleaning up a noisy battery rail. Key specifications of the TPS7B8750QDDARQ1 include a fixed 5.0-V output, 500-mA continuous load capability, a wide 3-V to 40-V operating input range with 40-V absolute maximum, a low quiescent current optimized for always-on body modules, an integrated open-drain PG output with programmable delay or fixed threshold, and AEC-Q100 Grade 1 qualification for harsh automotive environments. The HSOIC-8 PowerPAD package provides an exposed thermal pad that must be soldered to a sufficient copper pour to achieve the rated thermal resistance; otherwise the LDO can enter thermal shutdown prematurely at high VIN-VOUT differential. Architecturally, the TPS7B8750QDDARQ1 uses a high-side P-channel MOSFET pass element, an internal bandgap reference, an error amplifier, and a PG comparator that monitors VOUT with a defined threshold window. The PG de-asserts during dropout, thermal shutdown, or current-limit events, giving a microcontroller reset or sequencer a clean digital view of rail health. The integrated reverse-current blocking and short-circuit protection make the device robust to the negative-voltage transients defined in ISO 7637-2 load-dump and jump-start test pulses. Typical applications include automotive body control modules (BCM), instrument cluster supplies, ADAS sensor rails, CAN/LIN transceiver power, and 12-V/24-V industrial battery-powered systems that need to survive load-dump transients. The PG pin can be wired to a microcontroller reset input for rail-sequencing or fault monitoring, while the wide 40-V input directly addresses ISO 7637-2 pulse and 24-V jump-start stress. When designing with this part, place input and output ceramic capacitors as close as possible to the IC pins to minimize parasitic inductance, and never omit the PowerPAD land pattern. Always verify the PG pull-up rail does not exceed the PG pin's absolute maximum, and confirm worst-case power dissipation at 24-V jump-start versus 12-V cranking.

Typical applications include radiation-tolerant point-of-load converters for space-grade FPGA core rails, satellite command-and-data-handling subsystems, distributed 12 V intermediate bus converters, and high-current synchronous-buck POL stages for processors and ASICs. Two TPS7H6200-SEP devices can be paralleled with the TPS7H5101-SEP controller to scale to 80 A, with additional phases for 160 A and beyond. When laying out this device, keep the input decoupling loop as small as possible and follow the land pattern and thermal via array shown in the manufacturer datasheet. The low-side current-sense output is referenced to the source of the low-side FET and must be conditioned externally before being fed back to the controller.

It accepts input voltages from 3.5 V to 60 V and uses peak current-mode control with a tight-tolerance, 200-mV internal reference voltage for accurate LED current sensing while minimizing power dissipation in the current-sense resistor. An LED driver IC is a specialized power-management device that regulates current rather than voltage to a string of light-emitting diodes. LED drivers typically belong to the broader category of switching converters (DC-DC regulators), where buck (step-down) topology is preferred for high-brightness LEDs when the input bus voltage exceeds the forward-voltage stack. Inside the TPS92510 family, the part supports analog and PWM dimming via a dedicated PWMIN pin, plus an integrated LED thermal foldback function that automatically reduces current as the LED array temperature rises, protecting the load without external thermistor circuits. Key features include ±3% LED current accuracy over the operating range, 100-kHz to 2.5-MHz adjustable switching frequency, dedicated PWM dimming input, and thermal-foldback input for direct NTC/PWM interface. Internal protections include cycle-by-cycle current limit, overtemperature shutdown, and undervoltage lockout. The exposed thermal pad (PowerPAD) keeps θJA low for a small-footprint MSOP package, simplifying single-layer PCB layouts. The TPS92510 uses peak current-mode control with an internal 200-mV reference, allowing a small external sense resistor that keeps conduction loss below 5% in typical 350-mA to 700-mA strings. The integrated 200-mΩ high-side MOSFET handles up to 1.5 A of peak switch current and supports continuous conduction mode at high duty cycles. A high-side sense scheme rejects ground-borne noise that would otherwise degrade current accuracy in long LED cables. Typical applications include architectural and commercial LED lighting, MR16/AR111 retrofit lamps, automotive interior/exterior lighting, signage and display backlighting, and emergency/portable lighting. The wide 60-V input tolerance also supports industrial 24-V/48-V nominal rails directly. When designing with this device, choose the inductor so that the converter operates in continuous conduction at the minimum expected LED current, and route the thermal pad to a 1-square-inch copper pour to keep junction temperature well below the 150 °C thermal shutdown threshold.

The wide 4.5 V to 65 V input range allows direct connection to 12 V and 24 V nominal buses as well as industrial 48 V rails, while the integrated 200 mOhm MOSFET simplifies the BOM and enables high step-down ratios in compact PCB areas. A buck LED driver is a switch-mode DC-DC converter that regulates the current through an LED string rather than the voltage across it, which provides uniform brightness regardless of forward-voltage variation between LEDs. Within the broader power-management IC (PMIC) hierarchy, the TPS92513HV sits in the LED-driver category, which is itself a subset of switching regulators alongside buck, boost, and buck-boost converters optimized for light-load efficiency. Key features include cycle-by-cycle overcurrent protection, thermal shutdown, an enable/shutdown pin, an analog adjust (ADJ) input for current programming, and a PWM dim input. The peak-current-mode control topology yields good line and load regulation and supports user-selectable switching frequencies via an external resistor. The HVSSOP-10 PowerPAD package exposes the die ground pad for low thermal resistance (about 45 C/W on a standard 2 oz. 4-layer board), which keeps junction temperatures in check at full 1.5 A output. Designers can also synchronize the device to an external clock for EMI-sensitive applications. Typical applications include architectural and commercial LED lighting, automotive interior and exterior LED drivers, industrial signage, emergency lighting, and 24 V track-lighting fixtures. The 65-V rating gives substantial transient headroom on 24 V industrial buses where load-dump-style surges are common. The wide VIN range also supports daisy-chained LED luminaires powered from a single high-voltage rail. When laying out the PCB, place the input ceramic bypass, the bootstrap capacitor, and the freewheeling Schottky diode as close to the IC as possible to minimize parasitic loop inductance. The exposed pad must be soldered to a copper pour spanning multiple thermal vias to keep junction temperatures within the 150 C thermal-shutdown limit during continuous 1.5 A operation.
TPS92515HVQDGQRQ1 - 65V 2A Buck LED Driver, AEC-Q100 | Texas Instruments
The Texas Instruments TPS92515HVQDGQRQ1 is a 65-V automotive 2-A shunt-PWM dimmable LED driver integrating an N-channel MOSFET, high-side current sense, and shunt PWM dimming circuitry, housed in a thermally-enhanced 10-pin HVSSOP (DGQ) PowerPAD package. It is designed for high-brightness LED lighting applications where efficiency, high bandwidth, PWM and/or analog dimming, and small PCB area are important. An LED driver is a power-management integrated circuit that regulates current through one or more LED strings to maintain consistent luminance regardless of input voltage, LED forward-voltage variation, or temperature. LED drivers sit hierarchically between DC-DC converters (broader switching-power category) and discrete linear current regulators; the buck (step-down) topology used in the TPS92515HV-Q1 family is the most common for high-current, moderate-to-high input-voltage strings because it delivers high efficiency (typically >90 percent) without the heat dissipation of linear regulators. Key features include a 4.5-V to 65-V operational input range, integrated 200-mOhm N-channel FET, constant-off-time peak-current control, analog and shunt-PWM dimming capability, and AEC-Q100 Grade 1 qualification (operating from -40C to +125C). The HVSSOP-10 PowerPAD package exposes a thermal pad that lowers junction-to-ambient resistance (theta_JA approximately 50 C/W on a 4-layer JEDEC board), enabling 2-A continuous LED current without an external heatsink in properly laid-out designs. The high-side current-sense scheme eliminates the need for a ground-side shunt and avoids ground-loop noise coupling in long LED-cable harnesses. The device uses constant-off-time peak-current control with a simple external RC network to program switching frequency, and the integrated FET removes a major source of layout-dependent ringing and EMI. Current calibration trims the nominal LED current at a single reference point, reducing string-to-string brightness mismatch that would otherwise require hand-binning. Typical applications include automotive headlamps, daytime running lights, rear combination lamps, and turn signals, plus industrial high-bay lighting and architectural fixtures operating from 12-V or 24-V buses. Industrial LED signage, machine-vision illumination, and emergency-vehicle light bars are additional high-volume use cases. When VIN is above the LED string forward voltage by only a few volts, the driver remains efficient; when VIN is significantly higher, the duty cycle shrinks and switching losses dominate, so thermal layout becomes critical.

It is qualified to AEC-Q100 Grade 1 and supports analog plus PWM dimming for precise brightness control in headlamp, daytime running light, and interior lighting systems. What is a buck LED driver? A buck (step-down) LED driver is a switching DC-DC converter that regulates current through a string of LEDs by chopping the input voltage down to the LED forward voltage plus headroom. Buck LED drivers sit inside the broader hierarchy: LED driver -> lighting IC -> power management IC -> semiconductor. Compared with linear LED drivers they achieve much higher efficiency at large VIN-VOUT deltas, which is critical for automotive 12-V/24-V battery rails. Key features include a 42-V absolute maximum input (4.5-V to 42-V operating range), 2-A continuous switch current, integrated 250-mOhm N-channel FET, high-side current sensing for ground-referenced LED cathodes, 100:1 analog dimming range, and 1000:1 PWM dimming range via an external shunt FET. Cycle-by-cycle current limit and thermal shutdown provide fault protection. According to TI's product page, the HVSSOP-10 PowerPAD delivers a junction-to-ambient thermal resistance of approximately 47 C/W on a standard JEDEC 4-layer board. The TPS92515QDGQRQ1 uses peak-current-mode control with internal slope compensation to maintain stability across the full duty-cycle range. The high-side sense scheme eliminates the need for a ground-side shunt, simplifying PCB routing and improving efficiency by 2-5% versus low-side sense designs. The shunt-FET PWM dimming input permits >1 kHz dimming frequencies without audible noise. Typical applications include automotive LED headlights, fog lamps, daytime running lights, rear combination lamps, and architectural or industrial lighting that requires AEC-Q100 reliability. The wide VIN range also supports industrial 24-V nominal bus systems. When designing with this device, allocate at least 1 square cm of copper pour under the PowerPAD and use low-ESR ceramic input capacitors to handle the buck-switching ripple. Verify that the LED string forward voltage leaves sufficient headroom (typically >1.5 V) for current-sense accuracy at minimum VIN.

It operates across 9 V to 18 V nominal supply (with transient tolerance to 40 V) and integrates full diagnostics and protection features, including open-LED, short-to-GND, short-to-VBAT, and thermal shutdown. What is a linear LED driver? A linear LED driver is a constant-current regulator that places the LED string in series with a pass transistor whose conduction is modulated to maintain a programmed current. Unlike switching drivers, linear regulators introduce no EMI and no switching ripple, which makes them ideal for noise-sensitive analog lighting and for meeting CISPR 25 EMI limits in automotive modules. The TPS92630-Q1 belongs to the broader power management IC family (LED driver -> constant-current driver -> lighting driver -> PMIC) and is optimized for medium-power automotive lighting subsystems. Key features include a 150 mA per-channel current set by a single external sense resistor, 1000:1 analog dimming range, 1000:1 PWM dimming at 200 Hz, individual channel enable/diagnostic pins, and a fault output (FAULT) that asserts on any protection event. The HTSSOP-16 PowerPAD package achieves a theta_JA near 38 C/W on a 4-layer JEDEC JESD51 board, enabling compact PCB layouts without an external heatsink at typical 60-100 mA operating currents. The TPS92630-Q1 uses three independent linear current sinks, each with its own diagnostic comparator and PWM latch. A shared reference and bias block minimize channel-to-channel mismatch. Internal slope compensation on the analog dimming input ensures monotonic response across the 1000:1 range and prevents current crowding in multi-string arrays. Typical applications include automotive rear combination lamps, daytime running lights, interior ambient lighting, and ADAS indicator LEDs. The wide 4.5 V to 40 V transient tolerance also makes it robust against load-dump events on 12 V automotive buses. When designing with this part, place the 1 uF VIN bypass capacitor close to the IC and route the PowerPAD copper pour to a low-impedance ground plane. Verify thermal performance under worst-case VIN and full-current operation, and use the FAULT pin for system-level diagnostics in compliance with ISO 26262 functional-safety requirements.

Proper PCB layout, including minimizing parasitic inductance and ensuring adequate thermal management, is critical for optimal performance.
TPS92691-Q1 - 65V AEC-Q100 LED Driver Controller | TI
The Texas Instruments TPS92691-Q1 (TPS92691QPWPTQ1) is an automotive-qualified multi-topology LED driver controller supporting boost, buck, buck-boost, SEPIC, Cuk, and flyback topologies. It operates from a wide 4.5 V to 65 V input and integrates a 65-V rail-to-rail current sense amplifier with better than ±3% LED current accuracy over a junction temperature range of +25°C to +140°C and a 0 V to 60 V output common-mode range, enabling both high-side and low-side current sensing. The device is supplied in a 16-pin HTSSOP (PWP) package. An LED driver controller is a power management IC that regulates current through LED strings using a switching regulator architecture. Within the power management IC hierarchy, it sits between generic DC-DC controllers and dedicated constant-current LED drivers, adding dimming control, fault protection, and LED-specific features. Peak current mode control is a control technique in which the switch current is sensed and compared against an error-amplifier-derived threshold on a cycle-by-cycle basis, giving inherent cycle limiting and simple loop compensation. Key features include fixed-frequency peak current mode control with programmable switching frequency, programmable slope compensation for stable operation at duty cycles above 50%, programmable soft-start timing to limit inrush current, and a dedicated PWM dimming input that linearly varies LED brightness by modulating the duty cycle of the voltage applied to the PWM pin. Analog dimming is also supported, allowing flexible brightness control in automotive lighting systems. Architecturally, the integrated high-voltage current sense amplifier is the differentiating block: by tolerating a 60 V common-mode input, it removes the need for a dedicated low-side sense resistor path in high-rail strings and simplifies short-circuit diagnostics. The controller generates gate drive for an external MOSFET, so output power is set by external components rather than IC limits. Typical applications include automotive headlights, daytime running lights (DRL), fog lamps, LED backlighting, and industrial lighting driven from 12 V, 24 V, or 48 V automotive and industrial buses. Design consideration: choose the switching frequency and slope compensation together - higher frequency shrinks the inductor but increases switching loss; slope compensation must be set based on the sensed inductor current downslope to avoid subharmonic oscillation at duty cycles above 50%.

This controller class sits within the broader hierarchy of DC-DC switching controllers -> LED drivers -> power management ICs -> automotive-qualified analog semiconductors. Peak-current-mode control offers inherent cycle-by-cycle overcurrent protection and simplified loop compensation compared to voltage-mode control, making it well suited to the variable LED loads seen in adaptive driving beam and matrix-LED headlamp systems. Key features of the TPS92692QPWPRQ1 include analog and PWM dimming capability, high-side current sensing up to ±700 mV full-scale, an internal PWM generator that allows dimming without an external MCU, and spread-spectrum frequency modulation that reduces peak EMI emissions to ease CISPR 25 Class 5 compliance. The device supports both boost (step-up) and buck (step-down) operation from the same controller, allowing a single BOM to cover high-beam, low-beam, daytime running lights, and rear-lighting topologies. The HTSSOP-20 PowerPad package reduces theta_JA and supports sustained operation at high switching currents in space-constrained underhood environments. Architecturally, the device combines a precision transconductance error amplifier, a high-side current sense input (HI-SNS/LO-SNS), a programmable oscillator with spread-spectrum dithering, a PWM dimming latch, and a gate driver capable of driving external MOSFETs. This partitioning enables a designer to size the inductor, MOSFETs, and sense resistor for the specific string voltage and current without controller-side limitations. The internal soft-start and fault timer (with thermal shutdown, LED open/short detection, and fault output) simplify ASIL-relevant safety analysis for OEM headlamp modules. Typical applications include automotive front lighting (high beam, low beam, DRL), matrix-LED adaptive driving beam modules, rear lighting (tail, brake, turn), and high-current industrial LED strings. The AEC-Q100 Grade 1 rating makes it suitable for underhood operation across -40 °C to +125 °C ambient. When designing with this device, pay attention to PCB layout of the current-sense traces (Kelvin connection required to the sense resistor) and to thermal management of the PowerPAD - sustained boost operation at high duty cycle can dissipate several watts.
