ISL6561 Multi-Phase PWM Controller

DATASHEET ISL6561 Multi-Phase PWM Controller with Precision rDS(ON) or DCR Differential Current Sensing for VR10.X Application FN9098 Rev 6.00 November 10, 2015 The ISL6561 controls microprocessor core voltage regulation by driving up to 4 synchronous-rectified buck channels in parallel. Multi-phase buck converter architecture uses interleaved timing to multiply channel ripple frequency and reduce input and output ripple currents. Lower ripple results in fewer components, lower component cost.

ISL6561 Features

* a high bandwidth control loop and ripple frequencies of >4MHz to provide optimal response to the transients. Today’s microprocessors require a tightly regulated output voltage position versus load current (droop). The ISL6561 senses current by utilizing patented techniques to measure the voltage acr
