Multiphase PWM Controller for CORE Voltage Regulation
DATASHEET
FN9068 Rev 3.00 July 2004
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.
