ISL6322
ISL6322 is Four-Phase Buck PWM Controller manufactured by Renesas.
Four-Phase Buck PWM Controller with Integrated MOSFET Drivers and I2C Interface for Intel VR10, VR11, and AMD Applications
FN6328 Rev 2.00 Aug 2, 2007
The ISL6322 four-phase PWM control IC provides a precision voltage regulation system for advanced microprocessors. The integration of power MOSFET drivers into the controller IC marks a departure from the separate PWM controller and driver configuration of previous multiphase product families. By reducing the number of external parts, this integration is optimized for a cost and space saving power management solution.
One outstanding feature of this controller IC is its multi-processor patibility, allowing it to work with both Intel and AMD microprocessors. Included are programmable VID codes for Intel VR10, VR11, as well as AMD DAC tables. A unity gain, differential amplifier is provided for remote voltage sensing, pensating for any potential difference between remote and local grounds. The output voltage...
