ISL6263B Datasheet 5-bit Vid Single-phase Voltage Regulator

Manufacturer: Intersil (now Renesas)

Overview: ® 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 implementation area and lower ponent cost.

Key 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) should the inductor current attempt to flow negative. DEM is highly configurable and easy to set-up. A PWM filter can be enabled that prevents the switching frequency from entering the audible spectrum as.
