TPS65251RHAT Description

Short technical summary and product information.

The Texas Instruments TPS65251RHAT is a highly efficient synchronous triple buck converter. It operates with a wide input supply voltage range from 4.5 V to 18 V, making it suitable for various power applications.

 

This converter features three integrated buck converters capable of delivering continuous output currents of 3 A for Buck 1 and 2 A for Buck 2 and 3. The output voltage is adjustable, with a nominal reference accuracy of 1%. The switching frequency can be adjusted externally from 300 kHz to 2.2 MHz, allowing for design optimization.

 

The TPS65251RHAT is housed in a 40-pin VQFN package with dimensions of 6 mm x 6 mm. It is designed for surface mount applications and operates within a temperature range of -40°C to 125°C (TJ). The device includes features such as dedicated enables for each buck, external synchronization, and adjustable current limits.

 

This component is ideal for applications requiring multiple, high-current, regulated voltage rails from a single input source. Its synchronous rectification ensures high efficiency, reducing power loss and thermal management requirements.
