Single-Phase PWM Regulator for IMVP-6.5? Mobile
CPUs and GPUs
ISL62881C, ISL62881D
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 V CORE 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 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.
