ISL6326B 4-Phase PWM Controller

® Data Sheet April 21, 2006 ISL6326B FN9286.0 4-Phase PWM Controller with 8-Bit DAC Code Capable of Precision DCR Differential Current Sensing The ISL6326B 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, reduced power di.
