ISL6306, 4-Phase PWM Controller

DATASHEET ISL6306 4-Phase PWM Controller with 8-Bit DAC Code Capable of Precision rDS(ON) or DCR Differential Current Sensing FN9226 Rev 1.00 May 5, 2008 The ISL6306 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 components, lower component cost, reduce

ISL6306 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 ISL6306 senses current by utilizing patented techniques to measure the voltage
