ISL6565BCV

多相PWM控制器，带有精密的RDS（ ON）或DCR电流检测的VR10.X应用 Multi-Phase PWM Controller with Precision rDSON or DCR Current Sensing for VR10.X Application

The ISL6565A, ISL6565B controls microprocessor core voltage regulation by driving up to 3 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.
