PM6652

Overview

The PM6652 is a single-phase, step-down switching mode power supply (SMPS) controller manufactured by STMicroelectronics. Designed for Intel IMVP-6.5 and VR11 architectures, it supplies CPU and graphics core voltages. It features a high-precision 7-bit digital-to-analog converter (DAC). The device operates with an input voltage range of 4.5V to 36V. It is housed in a 32-pin VFQFPN-EP package measuring 5x5 mm. This component serves as a specialized power management integrated circuit for high-performance computing applications.
