Single-Phase PWM Regulator for IMVP-6.5™ Mobile CPUs and GPUs ISL62881HRTZ-T
The ISL62881 is a single-phase PWM buck regulator for miroprocessor or graphics processor core power supply. It uses an integrated gate driver to provide a complete solution. The PWM modulator of ISL62881 is based on Intersil's Robust Ripple Regulator (Rsup3/sup) technology™. Compared with traditional modulators, the Rsup3/sup™ 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.brbr The ISL62881 can be configured as CPU or graphics Vcore controller and is fully compliant with IMVP-6.5™ 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.brbr Maintaining all the ISL62881 functions, the ISL62881B offers VR_TT# function for thermal throttling control. It also offers the split LGATE function to further improve light load efficiency.
