ISL6322 Datasheet (Intersil) - Four-Phase Buck PWM Controller

ISL6322, Four-Phase Buck PWM Controller

® Data Sheet February 15, 2007 ISL6322 FN6328.1 Four-Phase Buck PWM Controller with Integrated MOSFET Drivers and I2C Interface for Intel VR10, VR11, and AMD Applications 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 exter

ISL6322 Features

* for optimal transient response to load apply and removal. One of these features is highly accurate, fully differential, continuous DCR current sensing for load line programming and channel current balance. Active Pulse Positioning (APP) modulation is another unique feature, allowing for quicker init
