ISL95812HRZ

Special Purpose Regulators Overview

The ISL95812HRZ is a multiphase PWM regulator controller designed for Intel VR12.5, VR12.6, and VR12.6+ CPUs. It utilizes the Robust Ripple Regulator (R3) architecture to deliver up to 90 A output current with an adjustable voltage range of 500 mV to 2.3 V. Operating within a supply voltage of 4.5 V to 28 V, the device supports a wide temperature range from -10°C to +100°C. Housed in a 32-pin QFN-EP package measuring 4x4 mm with a height of 0.95 mm, it is optimized for high-performance computing applications requiring precise core voltage regulation.
