Overview

The TPS62172QDSGRQ1 is an automotive-qualified, synchronous step-down DC-DC converter designed for applications with an input voltage range up to 17V. It utilizes the DCS-Control topology to provide a fixed 3.3V output at 500mA with high efficiency and excellent transient response.

Why Choose This Part

This regulator features a high 2.25MHz switching frequency which allows the use of small inductors and capacitors. Its DCS-Control topology ensures seamless transition between PWM and Power Save modes while maintaining a low 17uA quiescent current for extended battery life.

Applications

Automotive Infotainment
Provides a stable 3.3V rail for head units and cluster displays from standard vehicle battery inputs.
ADAS Sensor Modules
Powers radar, camera, and ultrasonic sensors in space-constrained automotive environments due to its small 2x2mm footprint.
Industrial Field Instrumentation
Suitable for 12V and 15V industrial rails requiring low quiescent current and high reliability.
Always-On Battery Systems
Ideal for systems requiring high efficiency at light loads through its integrated Power Save Mode.

Getting Started

When designing the PCB layout, place the input capacitor and high-frequency bootstrap capacitor as close as possible to the pins to minimize parasitic inductance. Evaluation can be performed using the TPS62170EVM series of development boards, though the fixed 3.3V version may require verification of the feedback pin configuration.

Also Consider

TPS62162QDSGRQ1 TITexas Instruments - Offers 1A output current in the same 2x2mm package if your power requirements exceed 500mA.
