TPS544B25RVFR Description

Short technical summary and product information.

The Texas Instruments TPS544B25RVFR is a high-performance synchronous buck converter from the SWIFT family, capable of delivering up to 20A of output current. It features a wide input voltage range of 4.5V to 18V and an adjustable output voltage ranging from 0.5V to 5.5V.

 

Key electrical specifications include a maximum duty cycle of 80% and a switching frequency that can be synchronized between 200kHz and 1MHz. The device supports advanced features such as PMBus communication, frequency synchronization, adaptive voltage scaling, adjustable current limit, differential remote sense, and power good indication. It also includes pre-bias start-up and adjustable soft-start capabilities.

 

Packaged in a 40-LQFN-CLIP (7x5) surface-mount package, the TPS544B25RVFR is designed for efficient operation with a typical quiescent current of 0.0095A. The operating temperature range is -40°C to 125°C (TJ). Its robust design makes it suitable for various power management applications requiring high current density and precise voltage regulation.
