Overview

The ISL62884CHRTZ is a single-phase PWM buck regulator for miroprocessor core power supply. It uses an integrated gate drivers to provide a complete solution. The PWM modulator of ISL62884CHRTZ 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 ISL62884CHRTZ is fully compliant with IMVP-6™ specifications. It responds to DPRSLPVR signals by 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 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.
