March 8, 2010 Single-Phase PWM Regulator for IMVP-6.5в„ў Mobile CPUs and GPUs
The ISL62881C provides a complete solution for
microprocessor and graphic processor core power
supply with it’s integrated gate drive. Based on
Intersil’s Robust Ripple regulator (R3™) technology,
the PWM modulator compared to traditional
modulators, has faster transient settling time, variable
switching frequency during load transients and has
improved light load efficiency with its ability to
automatically change switching frequency. Features Fully compliant with IMVP6.5в„ў, the ISL62881C is
easily configurable as a CPU or graphics VCORE
controllers by offering: responds to DPRSLPVR signals
by entering/exiting diode emulations mode; reports
regulator output current via the IMON pin; senses
current by using a discrete resistor or the inductor;
over-temperature thermal compensation of DCR, using
a single NTC thermistor; differential sensing to
accurately monitor and adjust processor die voltage;
minimizes body diode conduction loss in diode
emulation mode with it’s adaptive body diode …
