Overview

The TPS54202DDCR is a synchronous buck switching regulator designed for step-down applications with a wide input voltage range from 4.5V to 28V. It supports a continuous output current of up to 2A and features integrated high-side and low-side MOSFETs to minimize external component count. The device utilizes a fixed 500kHz switching frequency with integrated spread spectrum technology to improve EMI performance.

Why Choose This Part

This regulator integrates both MOSFETs (148mOhm and 78mOhm) and internal loop compensation, significantly reducing the external Bill of Materials and PCB area. Its advanced Eco-mode pulse skipping maintains high efficiency at light loads, while the hiccup-mode overcurrent protection ensures robust thermal management during fault conditions.

Applications

White Goods and Appliances
Provides stable low-voltage rails for microcontrollers and sensors from standard 12V or 24V DC bus architectures.
Consumer Electronics
Ideal for set-top boxes, portable media players, and chargers requiring high-efficiency power conversion in a small footprint.
Industrial Power Systems
Serves as a reliable local point-of-load regulator for distributed power systems and 24V industrial control bus rails.
Battery-Powered Equipment
Leverages low 45uA operating quiescent current and 3uA shutdown current to extend battery life in idle states.

Getting Started

When designing a PCB for the TPS54202DDCR, prioritize placing the input ceramic bypass capacitors as close as possible to the VIN and GND pins to minimize high-frequency noise. The output voltage is set via an external resistor divider connected to the FB pin, which regulates to a 0.596V reference. Designers can use the TI WEBENCH Power Designer tool to simulate performance and generate custom schematics based on specific output requirements.
