ISL6556A - Optimized Multi-Phase PWM Controller

® Data Sheet December 29, 2004 ISL6556A FN9096.3 Optimized Multi-Phase PWM Controller with 6-Bit DAC for VR10.X Application The ISL6556A controls microprocessor core voltage regulation by driving up to 4 synchronous-rectified buck channels in parallel.

Multi-phase 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 dissipation, and sma
