Overview

The TPS54202H is a synchronous buck converter that operates with an input voltage range from 4.5V to 28V and provides a maximum output current of 2A. It features integrated high-side and low-side MOSFETs and utilizes peak current mode control to simplify compensation and design. The device is designed to reduce EMI through optimized switching speeds and is packaged in a space-saving 6-pin SOT-23 format.

Why Choose This Part

The TPS54202H offers high efficiency at light loads through its pulse-skipping feature and maintains low EMI with frequency spread spectrum (FSS) capabilities. Its small SOT-23-6 package combined with an internal compensation network significantly reduces the total bill-of-materials and board area. Advanced protection features include cycle-by-cycle current limit, frequency foldback, and thermal shutdown to ensure robust operation.

Applications

Distributed Power Systems
Provides local step-down regulation for 12V or 24V bus rails in industrial and communication hardware.
White Goods
Efficiently powers control logic and sensors in home appliances where small PCB footprint is required.
Consumer Electronics
Regulates battery or wall-adapter inputs for set-top boxes, digital TVs, and smart speakers.
Industrial Power Supplies
Serves as a compact point-of-load regulator for PLCs and industrial automation modules.

Getting Started

Engineers can evaluate this part using the TPS54202EVM-716 evaluation module to verify performance and thermal characteristics. For custom designs, TI WEBENCH Power Designer provides automated component selection and simulation based on specific input/output requirements. Ensure that the input bypass capacitors are placed as close as possible to the VIN and GND pins to minimize switching noise.
