Overview

The TPS54302DDCR is a 4.5V to 28V input, 3A output synchronous buck converter designed for high efficiency in a compact SOT-23-6 package. It integrates both high-side and low-side MOSFETs and utilizes a fixed 400kHz switching frequency with internal compensation to minimize external component count.

Why Choose This Part

The device features integrated frequency spread spectrum (FSS) to significantly reduce EMI signatures, simplifying regulatory compliance. Its internal 5ms soft start and hiccup-mode overcurrent protection provide robust system reliability without requiring external timing components.

Applications

12V and 24V Distributed Power Systems

Efficiently steps down standard industrial and automotive bus voltages to logic levels.

Consumer Electronics

Provides a compact power solution for set-top boxes, LCD displays, and home appliances.

Battery-Powered Equipment

Utilizes Eco-mode pulse skipping to maintain high efficiency during light-load and standby conditions.

Industrial Automation

Used in PLC modules and sensor hubs requiring reliable 3A point-of-load regulation.
