ISL62881C, ISL62881D Single-Phase PWM Regulator for IMVP-6.5™ Mobile CPUs and GPUs FN7596 Rev 0.00 March 8, 2010 The ISL62881C provides a plete 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 pared 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. Fully pliant with IMVP6.5™, 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 pensation of DCR, using a single NTC thermistor; differential sensing to accurately...
