STOD03ASTPUR ST Power Management IC | 12-UFDFN Exposed Pad | 3A Output, 2.7-5.5V Input

Product Overview

The STOD03ASTPUR is a high-efficiency, step-down DC-DC converter from STMicroelectronics, designed for portable and battery-powered applications. It integrates a power switch and synchronous rectifier to deliver up to 3A continuous output current. The device operates from an input voltage range of 2.7V to 5.5V, making it suitable for single-cell Li-Ion battery-powered systems. The output voltage is adjustable from 0.8V to VIN. Housed in a compact 12-UFDFN package with exposed pad for enhanced thermal performance, the STOD03ASTPUR offers high efficiency (up to 95%) and low quiescent current (40µA typical). Protection features include overcurrent, thermal shutdown, and under-voltage lockout.
