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.
The difference between the ISL6565A and the ISL6565B is that the ISL6565A utilizes rDS(ON) current sensing, while ...
