ST1S14PHR ST Step-Down Regulator | 8-HSOP | 3A, 4.5V-48V Input

Product Overview

The ST1S14PHR is a high-voltage, step-down DC-DC converter from STMicroelectronics, designed for applications requiring a compact and efficient power solution. It operates from an input voltage range of 4.5V to 48V and delivers up to 3A of continuous output current. The device is housed in an 8-pin HSOP package with exposed pad for enhanced thermal performance. Its internal compensation and high switching frequency (up to 850kHz) allow for a small external component count, making it ideal for space-constrained designs.
