Overview

The TPS62821DLCR is a high-efficiency synchronous step-down converter capable of delivering up to 1A of output current from an input voltage range of 2.4V to 5.5V. Utilizing TI's DCS-Control topology, it provides fast transient response and high output voltage accuracy for space-constrained power management designs.

Why Choose This Part

The device features a very low 4uA quiescent current and a Power Save Mode that maintains high efficiency across the entire load range. Its DCS-Control topology combines the benefits of hysteretic and voltage mode control for excellent transient performance and 1% feedback voltage accuracy.

Applications

Point-of-Load Regulation
Efficiently stepping down 3.3V or 5V rails to lower core voltages for FPGAs, DSPs, and microcontrollers.
Battery-Powered IoT Devices
Extending battery life in portable equipment using the 4uA quiescent current and Power Save Mode during light loads.
Optical Modules
Providing stable, low-noise power in small form factor networking hardware due to its compact 1.5mm x 2.0mm package.
Solid State Drives (SSD)
Managing power rails for flash controllers and memory where high efficiency and small footprint are critical.

Getting Started

To evaluate this regulator, use the TPS62821EVM-005 evaluation module which provides a reference layout for the 8-pin VSON package. Designers should place the input capacitor as close as possible to the VIN and GND pins to minimize parasitic inductance and ensure EMI compliance.
