DATASHEET ISL6263A 5-Bit VID Single-Phase Voltage Regulator with Power Monitor for IMVP-6+ Santa Rosa GPU Core FN9284 Rev.3.00 Jul 8, 2010 The ISL6263A IC is a Single-Phase Synchronous-Buck PWM voltage regulator featuring Intersil’s Robust Ripple Regulator (R3) Technology™.

The ISL6263A is an implementation of the Intel® Mobile Voltage Positioning (IMVP) protocol for GPU Render Engine core power.

Integrated power monitor, droop amplifier, MOSFET drivers, and bootstrap diode result in smaller

ISL6263A 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 ISL6263A automatically enters diode emulation mode (DEM) shou
