ISL6261ACRZ

Special Purpose Regulators Overview

The ISL6261ACRZ is a single-phase core voltage regulator designed for Intel IMVP-6 mobile CPUs. It implements Intersil’s patented R3 Technology, utilizing a robust ripple modulator that commands variable switching frequency during load transients to achieve faster response times compared to traditional multi-phase regulators. The device features embedded gate drivers with 2A driving capability and supports precision VID inputs ranging from 0.300V to 1.500V in 12.5mV steps. It includes lossless inductor DCR current sensing, differential remote voltage sensing at the CPU die, and comprehensive protection against overvoltage, undervoltage, and overcurrent conditions.
