FAN5068 - DDR-1/DDR-2 plus ACPI Regulator Combo

Description

The FAN5068 DDR memory regulator combines a highefficiency PWM controller to generate the supply voltage, VDDQ, and a linear regulator to generate VTT, the termination voltage.

Synchronous rectification provides highefficiency over a wide range of load currents.

Features

  • PWM regulator for VDDQ (2.5V or 1.8V).
  • Linear LDO regulator generates VTT = VDDQ/2, 1.5A Peak sink/source capability.
  • 1 independent programable ULDO controllers driving external N-Channel MOSFET.
  • ACPI drive and control for 5V DUAL generation.
  • 3.3V Internal LDO for 3V-ALW generation.
  • 300kHz fixed frequency switching.
  • RDS(ON) current sensing or optional current sense resistor for precision over-current detect.
  • Internal Synchro.
