ISL95869HRTZ

Special Purpose Regulators Overview

The ISL95869HRTZ is a switching controller designed for Intel IMVP9 processor power rails. It features the Robust Ripple Regulator (R3) modulation technology, supporting configurable 1, 2, or 3-phase operation with two integrated gate drivers and provision for an external driver. The device operates within a +4.5V to +25V input range and communicates via SVID. Key electrical parameters include a maximum switch frequency of 750kHz, a typical rise/fall time of 8ns for drivers, and an operating temperature range of -10°C to +100°C. It utilizes a 32-lead Thin QFN package.
