TPS560430XDBVR 개요
A synchronous buck converter is a switching DC-DC topology that uses actively controlled high-side and low-side MOSFETs to step down a higher input voltage to a lower regulated output voltage. Buck converters belong to the broader class of voltage regulators within power management ICs (PMICs), and the synchronous variant replaces the conventional Schottky rectifier with a low-side MOSFET to improve efficiency, especially at light loads. SIMPLE SWITCHER is TI's family designation for easy-to-use, externally-compensated, wide-Vin synchronous buck ICs aimed at general-purpose point-of-load regulation.
Key features of the TPS560430XDBVR include 0.6A continuous load capability, 1.1 MHz typical switching frequency (with a 2.1 MHz sibling option in the family), pulse frequency modulation (PFM) for light-load efficiency, an enable pin for power sequencing, internal soft-start, and thermal shutdown. The 6-pin SOT-23-6 footprint enables use in space-constrained designs while still allowing thermal dissipation for a 0.6A load on a properly sized copper pour.
Technically, the TPS560430 uses peak current-mode control with internal compensation, a precision bandgap reference, and adaptive dead-time control between the high-side and low-side FETs to prevent shoot-through. The wide 4V-36V input range and 0.6A output deliver a flexible platform for 24V industrial buses, 12V automotive systems, and battery-powered applications where the input can vary widely during transients.
Typical applications include industrial 24V sensor and actuator rails, automotive infotainment and body controllers, point-of-load regulation after a higher-voltage bus, and general-purpose 5V/3.3V rails in PLC and factory automation modules. The wide input margin accommodates both nominal and transient conditions without requiring pre-regulation.
When designing with this part, ensure the input capacitor handles the 36V maximum and the inductor is rated for the 0.6A peak current. Use the WEBENCH® Power Designer tool to size L, Cin, Cout, and feedback resistors for the specific VIN/VOUT combination.

일반적인 애플리케이션
TPS560430XDBVR 적합 용도: 6 애플리케이션s: Industrial 24V Sensor and Actuator Rails, Automotive Body and Infotainment Electronics, Point-of-Load Regulation After 24V/12V Distribution, Battery-Powered Portable Equipment, LED Driver Bias Supply, Factory Automation and PLC Modules.
Industrial 24V Sensor and Actuator Rails
The TPS560430XDBVR's 4 V to 36 V input range and 0.6 A continuous output deliver clean point-of-load rails for industrial 24 V sensors, valve actuators, and PLC I/O modules. The wide input tolerance handles the voltage excursions common on factory 24 V buses, eliminating the need for a pre-regulator. With 1.1 MHz switching and integrated synchronous MOSFETs, the part fits in a compact SOT-23-6 footprint next to the sensor connector, and a 1 square-inch copper pour sustains thermal performance at full 0.6 A load. Place the input capacitor close to VIN and use a 4.7 uH inductor to keep ripple below 30 mV at full load.

Automotive Body and Infotainment Electronics
The TPS560430XDBVR handles 12 V automotive rails with load-dump transients up to 36 V, making it suitable for body controllers, infotainment head units, and LED driver bias supplies. Its 0.6 A continuous output is well-matched to powering microcontroller rails, CAN transceivers, and small display subsystems directly from the battery bus. The AEC-Q100 variant (TPS560430YFQDBVRQ1) extends qualification for harsher automotive environments. Designers should add an input TVS and bulk capacitor rated for 36 V minimum, and route the SW node trace away from sensitive analog signals.

Point-of-Load Regulation After 24V/12V Distribution
In distributed power architectures, the TPS560430XDBVR sits downstream of an isolated or non-isolated front-end converter and produces local 5 V, 3.3 V, or 1.8 V rails for FPGAs, MCUs, and analog ICs. Its 4 V to 36 V input window accepts a wide range of intermediate bus voltages, and the synchronous topology reaches 90%+ efficiency at typical load currents. Use the WEBENCH® Power Designer tool to size the inductor and feedback divider for your specific VIN/VOUT combination. The small SOT-23-6 footprint enables placement adjacent to the load IC for optimal transient response.

Battery-Powered Portable Equipment
The TPS560430XDBVR's PFM light-load mode maximizes efficiency at low current, extending battery life in portable test equipment, hand-held instruments, and low-duty-cycle IoT edge nodes. With a quiescent current of typically tens of microamps and 0.6 A peak capability, the part efficiently handles both sleep-mode housekeeping loads and short transmit-mode bursts. The 4 V minimum input accepts 1S Li-ion or multi-cell NiMH packs through the usable discharge range. Disable the output with the EN pin when the system is in deep sleep to minimize battery drain below the PFM threshold.
추천
LED Driver Bias Supply
The TPS560430XDBVR provides a constant-voltage bias rail for LED driver ICs and constant-current LED strings in architectural lighting, signage, and backlight applications. Its 0.6 A continuous output is sufficient for driving multiple LED channels through downstream constant-current regulators, and the wide 4 V-36 V input accepts both 12 V and 24 V lighting bus voltages directly. The 1.1 MHz switching frequency allows small ceramic bypass capacitors without audible noise concerns. Use the adjustable output to set the precise bias voltage your LED driver requires, typically 12 V or 24 V.
추천
Factory Automation and PLC Modules
The TPS560430XDBVR powers logic rails inside PLC modules, HMI panels, and industrial Ethernet gateways where 24 V field power must be reduced to 5 V or 3.3 V for the onboard MCU and communication ICs. Its 36 V tolerance handles the voltage spikes seen on long industrial cable runs, and the 0.6 A output supports typical MCU + PHY + isolation IC loads. The synchronous topology reduces heatsinking requirements compared to non-synchronous alternatives, important for sealed IP67 enclosures. Add a reverse-polarity protection FET at the input and a TVS clamp rated for 36 V to meet industrial EMC surge requirements.

설계 노트
Decouple the VIN pin with at least a 1 uF X7R ceramic capacitor rated for 36 V or higher, placed within 2 mm of the pin to handle the 1.1 MHz switching ripple. The output capacitor selection depends on the desired ripple voltage: a 10 uF ceramic handles most 5 V/3.3 V outputs at 0.6 A with <30 mV ripple. For wide-input designs (above 24 V), add an electrolytic bulk capacitor at VIN to absorb the inrush current and damp the input voltage ringing during load transients.
At VIN=12V, VOUT=5V, and 0.6 A load, the TPS560430XDBVR dissipates approximately (12-5) * 0.6 = 4.2 W. The SOT-23-6 package requires a copper pour of at least 1 square inch (645 mm^2) on the top layer to keep junction temperature rise below 50 C at 25 C ambient. Estimated junction-to-ambient thermal resistance on a 1 sq-inch pour is around 50 C/W, giving a 210 C junction rise - so full-load operation above 25 C ambient needs additional copper or forced airflow.
Route the SW node trace as short and wide as possible, keeping it on the top layer and away from the FB trace to minimize noise coupling. Place the bootstrap capacitor (typically 100 nF) directly between BST and SW, with the ground return of the input capacitor tied to the IC GND pin before spreading to the system ground. Use a 4-layer PCB with a dedicated ground plane if available; a 2-layer board with a ground pour under the IC is acceptable for prototypes.
Do not exceed the 36 V absolute maximum on VIN, even during load-dump transients - add a TVS diode (e.g., SMBJ33A) if the upstream protection is uncertain. The feedback resistor divider should use 1% or better tolerance resistors to maintain output accuracy; a typical 5 V output uses R_top=549 kohm and R_bot=100 kohm for the 0.8 V internal reference. Do not omit the BST capacitor - the high-side gate drive requires it to switch properly, and the part will not regulate without it.
