Monolithic Power Systems MP2935

Description

MP2935 is a high-efficiency, 4-phase, synchronous, buck-switching PWM controller with an SVID interface for high-performance Intel processors. The multi-phase PWM output signals can be configured for up to 4-phaseoperation with interleaved switching.MP2935 adopts three-logic-level PWM outputs for enhanced noise immunity and flexible fault management. Depending on the power states set by SVID command, the multi-phase channel can switch between multiphase and singlephase operation. In addition, MP2935 supports programmable load-line resistance. As a result, the output voltage is always optimally positioned for a load transient.The chip also provides accurate and reliable short-circuit protection with adjustable current limit threshold and a delayed VR_RDY output that is masked during on-the-fly output voltage changes to eliminate false triggering. MP2935performance is specified over the junctiontemperature range of -10°C to 125°C. The chipis available in 40-lead QFN package.
