TPS51225BRUKR Description

Short technical summary and product information.

The Texas Instruments TPS51225BRUKR is a dual synchronous step-down (buck) controller designed for efficient power management. It features integrated 5V and 3.3V LDOs, each capable of supplying 100mA, and supports a wide input voltage range from 5.5V to 24V.

 

This controller utilizes an adaptive on-time D-CAP mode control architecture with selectable switching frequencies of 300kHz or 355kHz. It offers key features such as light load efficiency, power good indication, and synchronous rectification. The device is housed in a 20-WQFN package with a 3mm x 3mm footprint, suitable for surface mount applications.

 

Additional features include ±1% reference accuracy, internal soft-start, and comprehensive protection mechanisms including OVP, UVP, and OCP. The TPS51225BRUKR is designed for applications requiring multiple voltage rails and efficient power conversion.
