TITPS62162QDSGRQ1

Overview

The TPS62162QDSGRQ1 is an automotive-qualified, synchronous step-down DC-DC converter optimized for high power density applications. Utilizing the DCS-Control topology, it provides a fixed 3.3V output from input voltages up to 17V with a 1A continuous output current capability. This AEC-Q100 qualified regulator is specifically designed for functional safety-capable systems requiring high efficiency across the entire load range.

Why Choose This Part

The DCS-Control topology combines the advantages of hysteretic and voltage mode control to provide excellent transient response and AC load regulation. With a high switching frequency of 2.25MHz, engineers can utilize smaller external inductors and capacitors to minimize PCB area. It also features a seamless transition into Power Save Mode and a 100% duty cycle mode for very low dropout operation.

Applications

Getting Started

Designers should follow the recommended layout in the datasheet to manage the high 2.25MHz switching frequency, specifically placing the input capacitor close to the VIN and GND pins. The TPS62160EVM-627 evaluation module can be used to validate performance, though it may require jumper configuration for fixed-output variants. For thermal management, ensure the thermal pad of the 8-WFDFN package is soldered to a large ground plane copper area.
