62881CHRTZ - ISL62881CHRTZ - Intersil

Single-Phase PWM Regulator for IMVP-6.5™ Mobile CPUs and GPUs

پی دبلیو ام تک فاز برای سی پی یو ها و جی پی یو های IMVP-6.5


General Description

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.

Fully compliant 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 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 withit’s adaptive body diode conduction time.

Need to aggressively reduce the output capacitor? The overshoot reduction function is user-selectable and can be disabled for those concerned about increased system thermal stress.

Maintaining all the ISL62881C functions, the ISL62881D offers VR_TT# function for thermal throttling control. It  also offers the split LGATE function to further improve light load efficiency.
