Product Description

The ISL6263ACRZ is a high-performance PWM controller from Intersil (now Renesas), designed as a voltage regulator IC for multiphase CPU power supply applications in servers, workstations, and high-end computing systems. This IC supports dual-output configurations with up to four interleaved phases per channel, optimizing efficiency and thermal management. Operating with an input voltage range of 4.5V to 24V, it generates tightly regulated core voltages from 0.8375V to 3.5V for modern processors. The device integrates adaptive voltage positioning, current balancing, and overcurrent/temperature protection, ensuring stable operation across industrial temperature ranges (-40°C to +85°C). Key advantages include precise voltage regulation, dynamic response to load transients, and compatibility with DrMOS power stages. However, it requires careful PCB layout and external components for optimal performance. The ISL6263ACRZ excels in systems demanding high-current delivery with minimal ripple, typically paired with multi-phase power stages to support CPU loads exceeding 100A.
