ISL6316 Enhanced 4-Phase PWM Controller

DATASHEET ISL6316 Enhanced 4-Phase PWM Controller with 6-Bit VID Code Capable of Precision rDS(ON) or DCR Differential Current Sensing for VR10 Application FN9227 Rev 1.00 Dec 12, 2006 The ISL6316 controls microprocessor core voltage regulation by driving up to 4 synchronous-rectified buck channels in parallel. Multiphase buck converter architecture uses interleaved timing to multiply channel ripple frequency and reduce input and output ripple currents. Lower ripple results in fewer component.

ISL6316 Features

* a high bandwidth control loop and ripple frequencies up to >4MHz to provide optimal response to the transients. Today’s microprocessors require a tightly regulated output voltage position versus load current (droop). The ISL6316 senses current by utilizing patented techniques to measure the voltage
