PWMs Support Multiphase Solutions For CPU And DDR Memory

April 2, 2014
The latest generation of International Rectifier’s CHiL digital pulse-width modulation (PWM) controllers meets Intel VR12 and VR12.5 specifications and supports multiphase designs from one to eight phases operating one to two loops.

The latest generation of International Rectifier’s CHiL digital pulse-width modulation (PWM) controllers meets Intel VR12 and VR12.5 specifications and supports multiphase designs from one to eight phases operating one to two loops.

These PMBus-enabled integrated PowIRstage solutions are designed for mid-range to high-end server, desktop, and computing applications. They can be used in combination with a choice of seven new PowIRstage products to deliver an end-to-end multiphase solution for CPU and double-data-rate (DDR) memory applications.

Enhanced features over the previous generation include significant expansion in the PMBus command set, reduction in quiescent current to enable higher peak efficiency, min/max telemetry recording, and an improved high-speed phase balance algorithm.
