The HIP6301V and HIP6302V control microprocessor CORE voltage regulation by driving up to four synchronous-rectified buck channels in parallel. Multiphase buck converter architecture uses interleaved timing to multiply ripple frequency and reduce input and output ripple currents. Lower ripple results in fewer components, lower component cost, reduced power dissipation, and a smaller implementation area. The HIP6301V is a versatile 2- to 4-phase controller and the HIP6302V is a cost-saving dedicated 2-phase controller.
