FAN5068 Product details

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.

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.
