ISL6263 Datasheet (Intersil Corporation) - 5-Bit VID Single-Phase Voltage Regulator

ISL6263, 5-Bit VID Single-Phase Voltage Regulator

® ISL6263 Data Sheet June 10, 2010 FN9213.2 5-Bit VID Single-Phase Voltage Regulator for IMVP-6+ Santa Rosa GPU Core The ISL6263 IC is a Single-Phase Synchronous-Buck PWM voltage regulator featuring Intersil’s Robust Ripple Regulator (R3) Technology™.

The ISL6263 is an implementation of the Intel® Mobile Voltage Positioning (IMVP) protocol for GPU Render Engine core power.

Integrated MOSFET drivers, bootstrap diode, and droop amplifier result in lower component cost and smaller implementation

ISL6263 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. To maximize light load efficiency, the ISL6263 automatically transitions between continuous-conducti
