ISL6327, Enhanced 6-Phase PWM Controller

DATASHEET ISL6327 Enhanced 6-Phase PWM Controller with 8-Bit VID Code and Differential Inductor DCR or Resistor Current Sensing FN9276 Rev 4.00 May 5, 2008 The ISL6327 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 components, lower component cost, redu
