, IR, introduced its latest generation of versatile, PMBus™ enabled, CHiL digital PWM controllers and integrated PowIRstage® solutions that significantly improve efficiency and reduce board space and component count in a variety of mid-range to high-end server, desktop and computing applications.
IR's new digital controllers meet Intel VR12 and VR12.5 specifications, and support multiphase designs from 1 to 8 phases operating 1 to 2 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 and an improved high-speed phase balance algorithm.
IR's latest PowIRstage® solutions integrate a high performance driver, control and synchronous MOSFETs with accurate, temperature compensated, on-chip current sense reporting and provide cycle-by-cycle over-current protection to self-protect against harsh circuit conditions such as inductor saturation events. Temperature sensing, reporting and over-temperature protection are also available in addition to a fault-flag output. These PowIRstage® devices are offered in 6x6mm PQFN packages, rated at 40A, 50A and 60A with over-molded and exposed top options available providing flexibility to achieve optimal thermal design.
