TITPS54202H
Overview
TPS54202H is a Texas Instruments switching buck regulator for stepping a higher DC input down to a lower regulated output. It is aimed at designs that need efficient point-of-load power conversion from an input rail in the 4.5 V to 28 V range. The part is a synchronous regulator, which helps reduce losses compared with a diode-based buck stage.
Why Choose This Part
TPS54202H is a practical choice when you need an efficient buck regulator with a fairly wide input range and a 2 A output capability. The synchronous topology simplifies thermal design versus non-synchronous solutions and can improve efficiency in compact layouts. It is well suited to space-constrained embedded power rails where a simple, dedicated switching regulator is preferred over a more complex PMIC.
Applications
Getting Started
Use the Texas Instruments datasheet and reference design notes as the starting point for inductor, output capacitor, and compensation choices. For evaluation, look for the corresponding TI EVM or a compatible buck regulator evaluation board if you want to validate transient response and layout before committing to PCB design. Route the high-di/dt switching loop carefully, keep feedback traces quiet, and follow the recommended layout closely to get the expected efficiency and stability.
