TPS40002DGQ Description

Short technical summary and product information.

The Texas Instruments TPS40002DGQ is a highly efficient DC DC Switching Controller designed for non-isolated synchronous buck regulators. It supports a wide input voltage range from 2.25V to 5.5V, with an output voltage capability as low as 0.7V.

 

This controller operates at a fixed switching frequency of 600kHz and features a Step-Down (Buck) topology. Key control features include adjustable soft-start and overcurrent limit, making it suitable for various power conversion needs. The device is designed to drive N-channel MOSFETs for both the primary buck switch and the synchronous rectifier.

 

Packaged in a 10-MSOP (0.118", 3.00mm Width) or 10-HVSSOP, the TPS40002DGQ is suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C (TA).
