CHiL MultiPhase ICs Product Overview

International Rectifier's innovative power management products enhance the power system architecture and translate into real tangible benefits for the computer & motherboard manufacturers (ODMs and OEMs) and the end user.

International Rectifier's multiphase buck PWM controllers and MOSFET drivers are the key components in high frequency voltage regulator (VR) designs for powering today’s high performance microprocessors (CPUs), memory point-of-loads (POL) and graphics processors (GPUs).

Increased efficiency, reduced board space, lower system bill-of-material (BOM) costs and reduced operating costs are achieved by the product features customized for each application. The intelligent mixed signal products provide flexible and scalable solutions for reduced design time and simplified inventory management.
