TPS40009DGQR Description

Short technical summary and product information.

The Texas Instruments TPS40009DGQR is a synchronous buck controller designed for low-voltage, non-isolated power conversion. It operates within an input voltage range of 2.25V to 5.5V and features a fixed switching frequency of 600kHz.

 

This controller drives N-channel MOSFETs for both the primary buck switch and the synchronous rectifier, enabling high-efficiency power conversion. It incorporates features such as current limit, enable, and soft start for robust operation. The device is packaged in a 10-MSOP (or 10-HVSSOP) and is designed for surface mount applications.

 

With its step-down topology and synchronous rectification, the TPS40009DGQR is suitable for various power management applications requiring efficient voltage regulation. The operating temperature range is -40°C to 85°C (TA).
