TPS40009DGQ Description

Short technical summary and product information.

The TPS40009DGQ from Texas Instruments is a DC DC switching controller designed for low-voltage, non-isolated synchronous buck regulators. It features a fixed-frequency voltage-mode control with a switching frequency of 600kHz.

 

This controller supports an input voltage range of 2.25V to 5.5V and can provide an output voltage as low as 0.7V up to 4V. Key electrical features include a maximum duty cycle of 83%, synchronous rectification, and control features such as current limit, enable, and soft start. The typical quiescent current is 1.5mA.

 

The TPS40009DGQ is housed in a 10-HVSSOP package and is designed for surface mount applications. It operates within an ambient temperature range of -40°C to 85°C. The package dimensions include a length of 6.55mm and varying widths and thicknesses depending on the specific tube carrier.

 

Applications for this controller include networking equipment, telecom equipment, base stations, servers, DSP power, and power modules. Its design facilitates higher efficiency through N-channel MOSFET drivers.
