The ISL6557 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-supply solutions available to power the latest industry-leading microprocessors.
Multi-phase buckconverter architecture uses interleaved timing to multiply ripple frequency and reduce input and output ripple currents.
Lower ripple results in lower total component cost, reduced dissipation, and smaller implementation area.
Preconfigured for 4-...
