A7986A ST DC-DC Converter | 8-HSOP-EP | 3A Output, 4.5V-38V Input

Product Overview

The A7986A is a step-down switching regulator from STMicroelectronics, designed for high-efficiency power conversion. It operates from an input voltage range of 4.5V to 38V and delivers up to 3A continuous output current. The device is housed in an 8-pin HSOP with exposed pad (8-HSOP-EP) for enhanced thermal performance. Its internal compensation and high switching frequency (up to 850kHz) allow for a compact solution with minimal external components.
