RT9040GQW Description

Short technical summary and product information.

The RICHTEK RT9040GQW is a sink/source tracking termination regulator specifically designed for low-cost and low-external component count systems. It features a high-speed operating amplifier for fast load transient response and requires a minimum 20µF ceramic output capacitance.

 

This regulator supports remote sensing functions and all features required for DDRI, DDRII, DDRIII, and Low Power DDRIII/DDRIV VTT bus termination according to JEDEC specifications. It includes an open-drain PGOOD signal to monitor output regulation and an EN signal for discharging VTT during S3 suspend-to-RAM states in DDR applications.

 

The RT9040GQW operates with an input voltage range of 1.1V to 3.5V and a VCNTL input voltage range of 2.375V to 5.5V. It provides an output tolerance of ±10mV and can source/sink up to 5A. The device is stable with MLCC capacitors.

 

Available in a thermal-efficient WDFN-10L 3x3 package, the RT9040GQW is suitable for applications such as Notebooks, Desktops, Servers, Telecom/Datacom equipment, GSM Base Stations, LCD-TVs, PDP-TVs, Copiers, Printers, and Set-Top Boxes.
