RT9040 - DDR Termination Regulator

Richtek

General Description

The RT9040 is a sink/source tracking termination regulator.

It is specifically designed for low-cost and low-external component count systems.

Key Features

required to power the DDRI / DDRII / DDRIII and Low Power DDRIII VTT bus termination according to the JEDEC specification. In addition, the RT9040 provides an open drain PGOOD signal to monitor the output regulation and an EN signal that can be used to discharge VTT during S3 (suspend to RAM) for DDR.

® RT9040 DDR Termination Regulator General Description The RT9040 is a sink/source tracking termination regulator. It is specifically designed for low-cost and low-external component count systems. The RT9040 possesses a high speed operating amplifier that provides fast load transient response and only requires a minimum 20μF of ceramic output capacitance. The RT9040 supports remote sensing functions and all features required to power the DDRI / DDRII / DDRIII and Low Power DDRIII VTT bus termination according to the JEDEC specification. In addition, the RT9040 provides an open drain PGOOD signal to monitor the output regulation and an EN signal that can be used to discharge VTT during S3 (suspend to RAM) for DDR applications .
