ST1PS02A1QTR ST DC-DC Converter | 12-TQFN (1.7x2) | 1.8V-5.5V Input, 400mA Output

Product Overview

The ST1PS02A1QTR is a high-efficiency step-down DC-DC converter from STMicroelectronics, designed for space-constrained and battery-powered applications. Housed in a compact 12-TQFN (1.7x2 mm) package, it delivers up to 400 mA output current with an input voltage range of 1.8V to 5.5V. The device integrates a synchronous rectifier and operates at a fixed 1.5 MHz switching frequency, enabling small external components. Its low quiescent current (typical 15 µA) and high efficiency (up to 95%) make it ideal for portable and IoT devices.
