Digital PWM controllers and integrated solutions present end-to-end solutions with PMBus

International Rectifier (El Segundo, CA) introduced its latest generation of MBus-enabled, CHiL digital PWM controllers and integrated PowIRstage solutions that are said to significantly improve efficiency and reduce board space and component count in a variety of mid-range to high-end server, desktop and computing applications. The new digital controllers meet Intel VR12 and VR12.5 specifications, and support multiphase designs from one to eight phases operating one to two loops. These digital controllers can be used in combination with a choice of seven new PowIRstage products to deliver an optimized high-performance end-to-end multiphase solution for CPU and DDR memory applications.  These latest generation CHiL controllers offer enhanced features over the previous generation including:

• Significant expansion in the PMBus command set.
• Substantial reduction in quiescent current to enable higher peak efficiency.
• Min/max telemetry recording.
• An improved high-speed phase balance algorithm.
