PM6675ASTR ST Power Management IC | 24-VFQFN Exposed Pad | Dual Step-Down Controller

Product Overview

The PM6675ASTR from STMicroelectronics is a high-performance dual step-down controller designed for low-voltage power supply applications. It integrates two synchronous buck regulators with adjustable output voltages, making it ideal for powering core voltages in networking, telecom, and industrial systems. The device operates from a 4.5V to 28V input supply and delivers output voltages as low as 0.6V with high efficiency. Housed in a compact 24-VFQFN package with exposed pad for enhanced thermal dissipation, the PM6675ASTR offers a reliable solution for space-constrained designs.
