ISL6263B 5-Bit VID Single-Phase Voltage Regulator

® ISL6263B Data Sheet July 8, 2010 FN6388.3 5-Bit VID Single-Phase Voltage Regulator with Current Monitor for IMVP-6+ Santa Rosa GPU Core The ISL6263B IC is a Single-Phase Synchronous-Buck PWM voltage regulator featuring Intersil’s Robust Ripple Regulator (R3) Technology™. The ISL6263B is an implementation of the Intel® Mobile Voltage Positioning (IMVP) protocol for GPU Render Engine core power. Integrated current monitor, droop amplifier, MOSFET drivers and bootstrap diode result in smaller i.

ISL6263B Features

* of both fixed-frequency PWM and hysteretic PWM, delivering excellent light-load efficiency and superior load transient response by commanding variable switching frequency during the transitory event. For maximum conversion efficiency, the ISL6263B automatically enters diodeemulation mode (DEM) shoul
