FAN5078 - DDR/ACPI Regulator Combo

Datasheet Summary

Description

The FAN5078 DDR memory regulator combines a highefficiency Pulse-Width Modulated (PWM) controller to generate the memory supply voltage, VDDQ, and a linear regulator to generate termination voltage (VTT).

Synchronous rectification provides high efficiency over a wide range of load currents.

Features

  • PWM regulator for VDDQ (2.5V or 1.8) Linear LDO regulator generates VTT = VDDQ/2, 1.5A Peak sink/source capability AMT / M-state support Control to generate 5V USB ACPI drive and control for 5V DUAL generation 3.3V internal LDO for 3V-ALW generation 300 kHz fixed frequency switching RDS(ON) current sensing or optional current sense resistor for precision over-current detect Internal synchronous boot diode C.
