ST1S41PUR ST DC-DC Converter | 8-DFN(4x4) | 4A, 4.5-18V Input

Product Overview

The ST1S41PUR is a high-efficiency step-down DC-DC converter from STMicroelectronics, designed for applications requiring up to 4A output current. It operates from an input voltage range of 4.5V to 18V and provides an adjustable output voltage down to 0.8V. Housed in a compact 8-DFN (4x4mm) package, it integrates high-side and low-side power MOSFETs, minimizing external component count and board space.
