TPS51275BRUKR Description

Short technical summary and product information.

The Texas Instruments TPS51275BRUKR is a versatile dual-synchronous buck controller designed for efficient power management. It features integrated 5-V and 3.3-V LDOs, providing flexible output voltage options.

 

This controller supports an input voltage range of 5.5 V to 24 V and offers an output current capability of up to 20 A. It utilizes the D-CAP control mode for adaptive on-time operation, with selectable switching frequencies of 300 kHz and 355 kHz. The device includes features like light-load efficiency, power good indication, and synchronous rectification.

 

Designed for surface mount applications, the TPS51275BRUKR comes in a 20-WQFN (3x3 mm) package. It operates within an ambient temperature range of -40°C to 125°C and includes protection features such as OVP, UVP, and OCP for enhanced reliability. The built-in output discharge function and separate enable input simplify system design.
