TPS560430YDBVR 개요
What is a synchronous step-down DC-DC converter? A buck converter is a switched-mode power supply (SMPS) topology that steps a higher DC input down to a lower DC output. Synchronous buck converters replace the traditional rectifier diode with a low-side MOSFET, which significantly improves efficiency at light loads and reduces conduction losses. Within the broader power-management IC hierarchy, this part belongs to the SIMPLE SWITCHER® family - a category of point-of-load regulators designed for ease of use, low external component count, and predictable behavior in industrial and automotive distributed-power systems.
Key features include an internal compensation network that removes external compensation components, an EN pin for power sequencing and shutdown, and PFM (Pulse Frequency Modulation) at light loads to extend efficiency in idle conditions. The 2.1 MHz switching frequency (Y variant) keeps the converter above the AM band, simplifying input-filter design. Quiescent current is rated at approximately 80 µA typical, and the converter supports output voltages down to 1 V. The SOT-23-6 package is the industry-standard micro-outline footprint for low-power synchronous bucks.
The TPS560430YDBVR integrates control logic, gate drivers, and power FETs into one die, using peak current-mode control for stable loop response and predictable inductor selection. The architecture supports both forced PWM and PFM modes, allowing designers to trade light-load efficiency for predictable output ripple. The wide 4 V-36 V input range supports direct connection to industrial 24 V rails, automotive 12 V battery systems, and eMeters without an upstream pre-regulator.
Typical applications include industrial automation sensors, factory equipment modules, portable instrumentation, and automotive accessory power rails. The 600 mA rating suits sub-system loads such as microcontrollers, transceivers, and display backlights. The wide VIN range and small package also make it attractive for distributed POL (point-of-load) power in space-constrained designs.
When designing with this part, follow the datasheet's recommended inductor and capacitor values for the 2.1 MHz variant to maintain stability across the full duty-cycle range. Place the input bypass capacitor as close as possible to VIN and GND to minimize switching-node ringing and EMI.

Industrial Automation Sensor Modules
The TPS560430YDBVR's 4 V-36 V wide input range directly accepts industrial 24 V rail voltages, while the 2.1 MHz switching frequency keeps the fundamental above the AM broadcast band for simpler EMI filter design in factory sensor modules. The 80 µA quiescent current extends battery life in wireless sensor nodes that spend most of their time in standby. The integrated MOSFETs reduce the BOM to one inductor, two ceramic capacitors, and a feedback divider, fitting inside small IP65-rated sensor enclosures. Designers can place this converter as a point-of-load stage after a higher-voltage PLC backplane, supplying 3.3 V or 5 V rails to microcontrollers and analog front-ends. AEC-Q100 availability via TPS560430YFQDBVRQ1 enables sensor designs that bridge industrial and factory-floor environments.

Automotive Accessory Power Rails
The TPS560430YDBVR's 36 V maximum input handles load-dump transients in 12 V automotive battery systems, making it ideal for powering infotainment accessories, USB charging ports, and interior lighting modules. For AEC-Q100 automotive applications, the pin-compatible TPS560430YFQDBVRQ1 provides the same SOT-23-6 footprint with full automotive qualification. The 600 mA continuous output easily drives a small cluster of LEDs, a CAN transceiver, or a Bluetooth audio module. The wide input range allows direct connection to the battery without an upstream pre-regulator, saving board space and cost. Designers should add a TVS diode and input capacitor to handle ISO 7637-2 transient pulses common in automotive environments.
추천
Portable Instrumentation and Test Equipment
The TPS560430YDBVR's 600 mA output capability and small SOT-23-6 package suit handheld multimeters, oscilloscope probes, and portable data loggers where board space is at a premium. The wide 4 V-36 V input range accepts multi-cell battery packs (3S-8S Li-Ion) as well as bench-top DC supplies without a pre-regulator. The 80 µA quiescent current preserves battery runtime when the instrument is in standby between measurements. The synchronous architecture and integrated MOSFETs eliminate the external Schottky diode, reducing both BOM cost and assembly time. Designers can use the EN pin to sequence power-up with downstream analog stages, avoiding inrush-related ADC errors at measurement startup.

Factory Equipment Distributed POL
The TPS560430YDBVR fits distributed point-of-load applications in factory PLCs and I/O modules where 24 V backplane power is converted to 3.3 V or 5 V at the sub-system level. The SOT-23-6 package occupies less than 10 mm² of board area, allowing dense placement behind connectors and near DSP/FPGA cores. Peak current-mode control provides stable loop response even with ceramic output capacitors, which simplifies compensation design. The 2.1 MHz switching frequency keeps the fundamental above the AM band, easing conducted-emissions compliance with industrial EMC standards. Designers can parallel multiple TPS560430YDBVR devices on a single board for multi-rail supplies without cross-regulation issues.

Display Backlight and LED Driver Bias
The TPS560430YDBVR's 600 mA output and 1 V minimum output voltage suit LED driver bias supplies for small LCD and OLED displays. The 2.1 MHz switching frequency stays above the AM band, preventing audible interference from the backlight boost stage. Wide 4 V-36 V input allows direct connection to industrial 24 V rails or 12 V battery systems without pre-regulation. The SOT-23-6 footprint fits underneath the display connector, conserving board area in compact HMI panels. Designers can use the EN pin to coordinate display power-up with the panel's logic supply, avoiding inrush and latch-up issues during cold-start.
추천
IoT Edge Node and Smart Sensor Power
The TPS560430YDBVR's 80 µA quiescent current and wide VIN range suit battery-powered IoT edge nodes harvesting energy from solar panels or 12-24 V industrial sources. The synchronous buck topology and 2.1 MHz switching frequency enable compact PCB layouts that fit inside small sensor enclosures. Designers can use the EN pin to wake the converter from an external MCU's GPIO, achieving sub-µA standby when the node is sleeping. PFM mode at light load extends battery life during low-duty-cycle data acquisition. The SOT-23-6 footprint allows direct mounting beside coin-cell or Li-Ion battery holders in wearable form factors.

설계 노트
Place the input bypass capacitor (10 µF ceramic, X7R, 50 V rated) as close as possible to the VIN and GND pins - within 2 mm. The high-side MOSFET switching node SW can radiate EMI; keep the SW trace short and minimize the loop area between SW, the inductor, and the output capacitor. The feedback pin FB is high-impedance and noise-sensitive; route the FB trace away from SW and BST to avoid coupling. Use a ground pour on the top layer tied to the exposed pad (where present) and stitch vias to the inner ground plane for thermal dissipation.
At VIN = 24 V, VOUT = 5 V, IOUT = 600 mA, the converter dissipates approximately 11.4 W of waste power at 100% duty ratio load transients. The SOT-23-6 package has a θJA of approximately 200 °C/W on a standard JEDEC 4-layer board. The junction temperature can rise above 125 °C under sustained high-line, high-load conditions. To reduce thermal stress, add a copper pour under the exposed pad (or under the GND pin) of at least 100 mm², or choose TPS562210ADDFR with PowerPAD for higher thermal capacity at higher current loads.
Do not exceed the absolute maximum VIN of 38 V (per datasheet), as automotive load-dump pulses can reach 40 V transiently. Add a TVS diode (such as SMAJ33A) on the input for 12 V automotive systems. The EN pin must not be left floating - tie it to VIN through a 100 kΩ resistor, or drive it from a logic-level GPIO. The BST capacitor (typically 0.1 µF) must be placed close to the BST and SW pins; omitting it prevents high-side drive and causes output collapse.
