The ISL6557A provides core-
voltage regulation by driving up to four interleaved synchronous-rectified buck-converter channels in parallel.
Intersil multi-phase controllers together with Intersil
MOSFET drivers form the basis for the most reliable power-suppply solutions available to power the latest industry-leading microprocessors.
Multi-phase buck converter architecture uses interleaved timing to multiply ripple frequency and reduce input and output ripple currents.
