Overview

The TPS560430XFDBVR is a compact, synchronous step-down buck regulator from Texas Instruments designed to operate from an input voltage range of 4V to 36V. It delivers up to 600mA of output current at a high 1.1MHz switching frequency, allowing for the use of small external components in space-constrained designs.

Why Choose This Part

This regulator features integrated synchronous rectification to eliminate the need for an external diode, significantly reducing board space and heat. It includes internal compensation and hiccup-mode short circuit protection to simplify layout and improve system robustness.

Applications

Industrial Control Supplies
Ideal for stepping down 24V industrial rails to 5V or 3.3V logic levels for sensors and controllers.
Automotive Aftermarket Accessories
Provides efficient power conversion for dash cams and GPS units running from 12V vehicle power systems.
Point-of-Load Regulation
Distributed power architectures requiring high efficiency in a small SOT-23-6 footprint.
Appliances and White Goods
Used in standby power supplies where low shutdown current and reliability are essential.
