ISL6312, Four-Phase Buck PWM Controller

DATASHEET ISL6312 Four-Phase Buck PWM Controller with Integrated MOSFET Drivers for Intel VR10, VR11, and AMD Applications FN9289 Rev 6.00 February 1, 2011 The ISL6312 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

ISL6312 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
