FAN5068 Datasheet (Fairchild Semiconductor) - DDR-1/DDR-2 plus ACPI Regulator Combo

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

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.

Efﬁciency is further enhanced by using t
