ISL6307 6-Phase PWM Controller

DATASHEET ISL6307 6-Phase PWM Controller with 8 Bit VID Code Capable of Precision RDS(ON) or DCR Differential Current FN9224 Rev 0.00 March 9, 2006 The ISL6307 controls microprocessor core voltage regulation by driving up to 6 synchronous-rectified buck channels in parallel. Multiphase buck converter architecture uses interleaved timing to multiply channe.

Features

a high bandwidth control loop and ripple frequencies up to 6MHz to provide optimal response to the transients. Today’s microprocessors require a tightly regulated output voltage position versus load current (droop). The ISL6307 senses current by utilizing patented techniques to measure the voltage across the on resistance, RDS(ON), of the lower .
