TPS62745DSSR - 300mA Ultra-Low IQ Step-Down Converter | Texas Instruments
The Texas Instruments TPS62745DSSR is a 300 mA ultra-low quiescent-current synchronous step-down (buck) DC/DC converter housed in a 12-pin WSON (DSS) package with exposed thermal pad. It accepts a 3.3 V to 10 V input range and delivers a programmable output voltage of 1.8 V to 3.3 V via the VSEL pin, while achieving typically 360 nA quiescent current for sleep-mode efficiency in battery-powered applications. The device is targeted at low-power wireless systems that must ride through long idle periods on small cells such as CR2032, 2xAA, or Li-ion batteries. What is a step-down (buck) DC/DC converter? A buck converter is a switched-mode power supply (SMPS) topology that converts a higher input voltage to a lower regulated output voltage by storing energy in an inductor and switching it through synchronous MOSFETs at high frequency. Buck converters sit within the broader hierarchy of voltage regulators -> power management ICs -> semiconductors. Compared with linear regulators (LDOs), buck converters trade a small switching-ripple penalty for 80-95% efficiency across a wide VIN/VOUT differential, making them essential when battery energy is precious. Key features of the TPS62745DSSR include a sub-1 uA quiescent current, integrated MOSFETs (no external power switches), VSEL output-voltage switching for dynamic power-rail selection, and an input-voltage switch (VIN_SW) that lets the device ride through supply transients. Output current is rated to 300 mA continuous, with a 2.5 MHz typical switching frequency that allows the use of a tiny 1.0 uH inductor and small ceramic capacitors, minimising total solution footprint. The TPS62745DSSR uses TI's DCS-Control topology (Direct Control with Seamless transition into power-saving mode) to maintain high efficiency across the entire 1 mA to 300 mA load range. A dedicated power-good output, internal soft-start, and thermal shutdown protection complete the integration. The WSON-12 exposed-pad package offers a low thermal resistance path, supporting operation from -40 C to +125 C junction temperature. Typical applications include Bluetooth Low Energy (BLE) sensor nodes, wearable health monitors, energy-harvesting power conditioning, smart thermostats, and IoT endpoint devices powered by coin-cell or dual-AA batteries. The ultra-low IQ and high light-load efficiency directly extend battery life when radio duty-cycling dominates the average current draw. When designing with this part, select the inductor for both DC resistance and saturation current rating at peak load, and place the input/output ceramic bypass capacitors within 2 mm of the package to keep the feedback loop stable. Verify that the VSEL logic levels match the host MCU's GPIO rail before relying on dynamic voltage scaling. This page synthesises distributor pricing, drop-in WSON-12 alternatives, and practical low-power design notes that are not consolidated in the manufacturer datasheet, giving engineers a faster path from selection to qualified BOM.

A step-down converter (also called a buck converter) is a switch-mode DC/DC regulator that converts a higher input voltage to a lower output voltage with high efficiency by rapidly switching an inductor and rectifying the resulting waveform. As a member of the broader DC/DC converter family, it sits hierarchically under switching regulators, then voltage regulators, then power management ICs. This category is essential in modern battery-powered and space-constrained electronics because linear regulators waste VIN-VOUT * IOUT as heat, whereas a properly designed buck like the TPS62825 typically achieves 90%+ efficiency across most of its load range. Key features of the TPS62825DMQR include a best-in-class quiescent current of 4 µA (light-load), 2-A continuous output current, 2.4-V to 5.5-V input voltage range, output voltage adjustable from 0.6 V up to 4 V, 2.2-MHz fixed switching frequency, power-good output, and an enable pin that supports power sequencing. The device supports both forced PWM and power-save (DCM) operation, optimizing efficiency at light loads. The DCS-Control (Direct Control with Seamless transition into power-save mode) architecture combines the fast transient response of hysteretic control with the high efficiency of a pulse-frequency-modulated (PFM) light-load mode. The internal reference is trimmed to 1% accuracy over the -40 °C to +125 °C junction-temperature range, providing a tight output tolerance demanded by core-rail and SoC power requirements.

The device is pin-to-pin and BOM-to-BOM compatible with the rest of the TPS6282x family, allowing 1/2/3/4-A current scaling on a single PCB layout. Typical applications include 1-cell Li-ion / 2-cell alkaline battery-powered systems, USB Type-C powered accessories, solid-state drives, portable consumer electronics, and infotainment head units. The wide 2.4 V to 5.5 V input range lets a single device operate from a depleted Li-ion cell (2.5 V) all the way through USB VBUS (5 V) without a pre-regulator. When designing with this device, choose a 470 nH inductor and place input/output capacitors within 1 mm of the exposed thermal pad; the pad MUST be soldered to a top-layer copper pour to carry 4 A dissipation in still air. Always check the derating curves in the manufacturer datasheet to ensure the junction temperature stays below 125 C at worst-case load.

Within the broader taxonomy, a buck converter sits as a sub-type of DC-DC converter, which belongs to the family of voltage regulators, which itself is a category of power management integrated circuits (ICs). Buck converters are the dominant topology for battery-powered electronics because they achieve efficiencies of 80-95%, far higher than the linear regulators (LDOs) they often replace. Key features include the 120 nA IQ achieved in 100% duty-cycle mode for end-of-discharge battery operation, DCS-Control topology that combines voltage-mode and current-mode control for clean RF powering, a STOP pin that disables switching during noise-sensitive measurements, and Power Save Mode that reduces switching frequency at light load to maintain efficiency. The 1.8 MHz switching frequency allows small external inductors and ceramic-only capacitors, enabling a complete sub-1 cm-squared solution footprint. The output voltage is adjustable via an external resistor divider. Technically, the TPS62840 integrates high-side and low-side MOSFETs, a precision reference, and a programmable soft-start.

It uses DCS-Control topology with a typical switching frequency of 1.8 MHz, supporting small inductors and capacitors for compact IoT and wearable designs. The output voltage is adjustable down to 0.8 V, making it suitable for powering modern processors, MCUs, and radios from single-cell Li-ion or multi-cell alkaline sources. A step-down (buck) converter is a type of switched-mode power supply (SMPS) that efficiently steps a higher DC input voltage down to a lower DC output voltage by rapidly switching an inductor/capacitor energy-transfer network. Within the broader power management taxonomy, a buck converter sits under DC-DC converters, alongside boost, buck-boost, and LDO topologies. Compared with linear regulators, buck converters achieve much higher efficiency (often above 90%) at the cost of higher output ripple and switching noise; LDOs trade efficiency for ultra-clean output. The TPS62841 family targets the ultra-low-IQ segment where standby drain dominates total energy budget. Key features include 60 nA typical quiescent current (120 nA in 100% mode), 750 mA continuous output current, an operating input range of 1.8 V to 6.5 V, and an adjustable output from 0.8 V upward via an external resistor divider. Power-Save Mode maximizes light-load efficiency, while DCS-Control provides clean PWM operation at higher loads. Integrated MOSFETs and internal compensation reduce external component count to one inductor plus input/output capacitors. The TPS62841DLCR achieves peak efficiency above 90% at moderate loads and supports DCS-Control to cleanly power noise-sensitive radio blocks. Its 1.8 MHz typical switching frequency keeps the fundamental and harmonics well above the AM band, simplifying EMI filtering in space-constrained designs. Typical applications include battery-powered IoT sensors, wearable health monitors, Bluetooth/Zigbee/LoRa nodes, energy-harvesting systems, and always-on microcontroller rails. The wide input range also supports USB and 2x AA/AAA alkaline source designs where quiescent drain directly determines operating life. When designing with the TPS62841DLCR, ensure the inductor saturation current exceeds the peak switch current and that the input/output ceramic capacitors meet the datasheet's minimum effective capacitance after DC bias derating. Power-Save Mode is automatic, but the converter exits PFM at heavy load and re-enters cleanly; leave adequate copper for thermal relief of the exposed pad.

Key features include a peak current-mode control topology for fast transient response, a MODE/SYNC pin that accepts an external clock for frequency synchronization or selects forced-PWM versus auto-PWM operation, and a wide Vin range that simplifies designs powered from 3.3-V or 5-V rails or directly from automotive battery transients. The SOT-583 footprint (approximately 1.6 mm x 1.6 mm) keeps the solution area compact, and the 4-MHz switching frequency enables the use of small inductors and ceramic output capacitors. Typical automotive applications include ADAS sensor power rails, infotainment processors, body electronics modules, and rear-view camera supplies. The device also suits industrial point-of-load conversion and any 5-V distributed-bus system that needs high efficiency in a small area. When designing with this part, follow the datasheet's minimum on-time and minimum off-time limits carefully when setting the external frequency-adjust resistor; violating these can degrade regulation.

The device reaches up to 96% efficiency, addressing conversion loss in portable applications where battery life and thermal budget are tightly constrained. A buck-boost converter is a switched-mode DC-DC topology that seamlessly transitions between buck (step-down), boost (step-up), and buck-boost operation as the input voltage crosses the regulated output setpoint. Within the broader power management IC hierarchy, it sits above simple LDOs and single-mode buck converters, since it must maintain regulation when VIN is below, equal to, or above VOUT. This makes buck-boost ICs essential for battery-powered systems whose rail voltage crosses a fixed output during discharge, and it gives them a unique role above linear regulators in efficiency, and alongside but functionally distinct from standalone buck or boost converters. Key features of the TPS63000 include a 1.5 MHz fixed switching frequency that permits the use of small inductors and ceramic capacitors, an adaptive hysteresis-based PWM/PFM control that maximizes efficiency across the full load range, and a power-save mode that drops quiescent current substantially at light loads.

The QFN-10 (3 mm x 3 mm) package with an exposed thermal pad delivers low parasitic inductance and adequate thermal performance for the converter's continuous 1.6A switch current. The TPS63000 uses TI's proprietary control scheme, described in the manufacturer datasheet, that adjusts duty cycle and switching behavior automatically based on the input-to-output voltage ratio. At 3.3V VIN and 3.3V VOUT the device runs at approximately 95% efficiency at moderate loads, while at 2V VIN (near end-of-discharge of a Li-ion cell) the boost region still maintains roughly 90% efficiency. The exposed thermal pad enables direct PCB heat spreading, which keeps junction temperature rise manageable without an external heatsink. Typical applications include portable media players, handhelds and portable terminals, industrial metering, single-cell Li-ion powered equipment, two-cell alkaline or NiMH powered systems, sensor modules and low-power wireless data acquisition, and any system whose battery voltage range straddles the regulated output voltage. The wide VIN window and adjustable VOUT also suit USB peripherals that must operate at 3.3V from a 4.5V to 5.5V rail. When designing with this converter, pay close attention to inductor selection (a 1.5 uH to 2.2 uH shielded inductor is typically recommended) and ensure the input/output ceramic capacitors meet the minimum value and voltage derating requirements described in the manufacturer datasheet. Place both capacitors as close as possible to the IC pins and use a continuous ground plane under the exposed pad to minimize EMI and ensure proper thermal dissipation.

Key features include a fixed 3.3V output voltage, high efficiency up to 96%, and a low quiescent current of 50 µA. The device integrates synchronous rectification, which eliminates the need for an external Schottky diode, improving efficiency and reducing component count. It also features load disconnect, light-load efficiency, and undervoltage lockout (UVLO) with fixed thresholds. The TPS63021 operates over a junction temperature range of -40°C to +125°C. Technically, the TPS63021 uses a proprietary control architecture that seamlessly transitions between buck and boost modes, ensuring stable output voltage with minimal ripple. The 4A switches allow for high output currents, and the device can deliver up to 3A in boost mode from a 3.3V input. The VFDFN package with exposed pad provides excellent thermal performance, with a thermal resistance of 40°C/W, enabling compact designs without external heatsinks. Typical applications include portable electronics, battery-powered devices, and systems powered by supercapacitors. The TPS63021 is ideal for powering microcontrollers, sensors, and wireless modules in IoT devices, where input voltage varies widely. Its high efficiency extends battery life, and its small footprint saves board space. When designing with the TPS63021, ensure proper input and output capacitor selection to minimize ripple and maintain stability. Use low-ESR ceramic capacitors with sufficient voltage rating. The exposed pad must be soldered to a thermal land on the PCB for optimal heat dissipation.

The Texas Instruments TPS63900DSKR is a four-switch synchronous buck-boost converter with 400 mA maximum output current, an ultra-low 75 nA quiescent current, and 32 user-programmable output voltage settings from 1.8 V to 5 V, housed in a 10-pin WSON (DSK) exposed-pad package. It accepts an input voltage range of 1.8 V to 5.5 V and integrates an adjustable input current limit plus Dynamic Voltage Scaling (DVS), which lets the host step the output between two preloaded voltages during operation. A buck-boost DC-DC converter is a switching regulator topology that maintains a regulated output voltage whether the input voltage sits above, below, or equal to the output. Unlike a buck (step-down only) or boost (step-up only) regulator, the buck-boost uses four switches to seamlessly transition between modes, eliminating output-voltage transients during the mode boundary. Within the power management hierarchy, the TPS63900 belongs to the broader family of switching regulators (DC-DC converters) that also includes LDOs, charge pumps, and PMICs. Its 75 nA quiescent current makes it a member of the nano-IQ class favored by battery-powered IoT designs. Key differentiating features include single-mode operation that avoids the mode-switching transients and unpredictable inductor current ripple seen in many competing buck-boost parts, 32 selectable output voltages stored in a one-time-programmable (OTP) memory, true shutdown with 5 nA Iq, and an exposed thermal pad that lowers junction-to-ambient thermal resistance. The DVS pin toggles between two programmed Vout levels without software reload delay, an advantage for systems that must reduce the rail during sleep. Architecturally, the TPS63900 uses a peak-current-mode control loop with synchronous rectification. A single 1-µH inductor handles all four switching phases, reducing BOM cost. The internal MOSFETs are rated for the full 1.8-5.5 V input range, and the adjustable input current limit lets designers protect weak source batteries such as coin cells or energy harvesters. Typical applications include battery-powered IoT nodes, wearables, energy-harvesting sensor platforms, BLE/Zigbee radio power rails, ultra-low-power MCUs, and backup-power systems where the converter must hold regulation across a wide Vin swing. The combination of nano-Iq, DVS, and OTP-programmable outputs is especially well suited to designs that spend most of their life in standby and burst-transmit at higher loads. When designing with this part, follow the datasheet's recommended 1 µH inductor with low DCR (< 50 mΩ) and place the four ceramic bypass capacitors (2x 10 µF input + 2x 10 µF output minimum) within 2 mm of the package. Check the worst-case thermals at the maximum 400 mA load, since the WSON-10 package relies on PCB copper for heat spreading.
