Overview

The TPSM828301ARDSR is a highly integrated 1A power module that combines a synchronous step-down converter with a shielded inductor in a compact 3.0mm x 3.0mm MagPack package. It features TI's DCS-Control topology to deliver excellent transient response and high output voltage accuracy across a wide 2.25V to 5.5V input range. This module is designed to simplify PCB layout and minimize EMI by integrating essential noise-filtering capacitors and shielding.

Why Choose This Part

The MagPack technology effectively shields the inductor and IC, significantly reducing radiated EMI and simplifying regulatory compliance. Its DCS-Control topology ensures seamless transition between power-save and PWM modes while maintaining a precise 1 percent output voltage accuracy. The 9-pin QFN-FCMOD package requires minimal external components, drastically reducing the total solution footprint compared to discrete buck regulators.

Applications

Point-of-Load Regulation
Providing stable power to low-voltage rails for FPGAs, ASICs, and microprocessors in space-constrained designs.
Battery-Powered Devices
Optimizing efficiency with a 7uA quiescent current and 100% duty cycle mode for extended battery life.

Getting Started

To evaluate the performance of the module, use the TPSM828301EVM evaluation board which provides test points for transient response and efficiency measurements. Design engineers should consult the datasheet for recommended external capacitor placement to maintain stability and low output ripple. For thermal management, ensure the thermal pad is soldered to a large copper ground plane as specified in the layout guidelines.
