ISL6307B Datasheet (Renesas) - 6-Phase VR11 PWM Controller

ISL6307B, 6-Phase VR11 PWM Controller

DATASHEET ISL6307B 6-Phase VR11 PWM Controller with 8-Bit VID Code Capable of Precision RDS(ON) or DCR Differential Current Sensing for Applications in Which Supply FN9225 Rev 0.00 Mar 9, 2006 The ISL6307B 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 channel ripple frequency and reduce input and output ripple currents.

Lower ripple results in fewer

ISL6307B 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 ISL6307B senses current by utilizing patented techniques to measure the voltage
