Description
The ISL62882C is a multiphase PWM buck regulator for miroprocessor or graphics processor core power supply. The
multiphase buck converter uses interleaved phases 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 ISL62882C 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 R³â„¢ 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.
The ISL62882C can be configured as CPU or graphics Vcore controller and is fully compliant with IMVP-6.5™
