ISL62882HRTZ General Description

The ISL62882 is a multiphase PWM buck regulator for microprocessor 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 ISL62882 uses two integrated gate drivers to provide a complete solution. The PWM modulator is based on Renesas' 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 ISL62882 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 ISL62882 offers the FB2 function to optimize 1-phase performance. The ISL62882B has the same functions as the ISL62882, but comes in a different package.
