ISL6324A - Monolithic Dual PWM Hybrid Controller Powering AMD SVI

Key Features

  • a multi-phase controller to support uniplane VDD core voltage and a single phase controller to power the Northbridge (VDDNB) in SVI mode. Only the multi-phase controller is active in PVI mode to support uniplane VDD only processors. A precision uniplane core voltage regulation system is provided by a 2-to-4-phase PWM voltage regulator (VR) controller. The integration of two power MOSFET drivers, adding flexibility in layout, reduce the number of external components in the multiphase section. A s.

DATASHEET ISL6324A Hybrid SVI/PVI with I2C Monolithic Dual PWM Hybrid Controller Powering AMD SVI Split-Plane and PVI FN6880 Rev 1.00 May 14, 2010 The ISL6324A dual PWM controller delivers high efficiency and tight regulation from two synchronous buck DC/DC converters. The ISL6324A supports hybrid power control of AMD processors which operate from either a 6-bit parallel VID interface (PVI) or a serial VID interface (SVI). The dual output ISL6324A features a multi-phase controller to support uniplane VDD core voltage and a single phase controller to power the Northbridge (VDDNB) in SVI mode. Only the multi-phase controller is active in PVI mode to support uniplane VDD only processors.
