TPS40054PWPR Description

Short technical summary and product information.

The TPS40054PWPR from Texas Instruments is a synchronous buck controller with a wide input voltage range of 8V to 40V. This device is capable of delivering up to 20A of output current and operates at frequencies up to 1MHz. It features a maximum duty cycle of 94% and includes control features such as current limit, enable, frequency control, and soft start.

 

The controller is housed in a 16-HTSSOP package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C (TA). The TPS40054PWPR is designed for step-down (buck) topology and incorporates synchronous rectification for improved efficiency.

 

This part is noted as 'NOT RECOMMENDED FOR NEW DESIGNS' and is available for existing customers. New designs should consider alternate products like the LM25145, LM5145, or LM5146, which offer similar functionality with potentially improved performance or different pinouts.
