The Texas Instruments TPS543B20RVFR is a high-performance 25A synchronous buck converter from the SWIFT℡ family. It is designed for efficient power management, accepting an input voltage range of 4V to 19V and delivering an adjustable output voltage from 0.6V to 5.5V.
Key electrical features include an adjustable current limit, differential remote sense capability, and an integrated 4.1/1.9-m℡ stacked NexFET™ power stage. The device supports adjustable switching frequencies from 300 kHz to 2 MHz for standalone operation, and 300 kHz to 1 MHz when stacked. It also offers features like forced PWM, frequency synchronization, power good indication, pre-bias start-up, and soft start.
This converter is housed in a 40-pin LQFN-CLIP package measuring 7mm x 5mm, suitable for surface mounting. Its operating temperature range is -40°C to 125°C (TJ). The TPS543B20RVFR is designed for applications requiring high current density and precise voltage regulation.
