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 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.
The ISL62882C can be configured as CPU or graphics Vcore controller and is fully compliant with IMVP-6.5™

specifications. It responds to PSI# and DPRSLPVR signals by adding or dropping Phase 2, adjusting overcurrent
protection threshold accordingly, and entering/exiting diode emulation mode. It reports the regulator output current
through the IMON pin. It senses the current by using either discrete resistor or inductor DCR whose variation over
temperature can be thermally compensated by a single NTC thermistor. It uses differential remote voltage sensing to
accurately regulate the processor die voltage. The unique split LGATE function further increases light load efficiency.
The adaptive body diode conduction time reduction function minimizes the body diode conduction loss in diode
emulation mode. User-selectable overshoot reduction function offers an option to aggressively reduce the output
capacitors as well as the option to disable it for users concerned about increased system thermal stress. The
ISL62882C offers the FB2 function to optimize 1-phase performance.
