ISL62882,pdf datasheet (Multip

The ISL62882 is a multiphase PWM buck regulator for
miroprocessor core power supply. The multiphase buck
converter uses interleaved phase to reduce the total output
voltage ripple with each phase carrying a portion of the total
load current, providing better system performance, superior
thermal management, lower component cost, reduced power
dissipation, and smaller implementation area. The ISL62882
uses two integrated gate drivers to provide a complete solution.
The PWM modulator is based on Intersil's Robust Ripple
Regulator (R3) technology™. Compared with traditional
modulators, the R3™ modulator commands variable switching
frequency during load transients, achieving faster transient
response. With the same modulator, the switching frequency is
reduced at light load, increasing the regulator efficiency.
