The Texas Instruments TPS548D22RVFR is a high-performance synchronous buck converter from the SWIFT™ family. It is designed for applications requiring high current density and efficiency, capable of delivering up to 40A of continuous output current.
This converter features a wide input voltage range from 1.5V to 16V, with an additional input bias voltage range of 4.5V to 22V. The output voltage is adjustable from 0.6V to 5.5V, offering flexibility for various power supply designs. Key electrical specifications include selectable switching frequencies (425 kHz, 650 kHz, 875 kHz, and 1.05 MHz), a typical quiescent current of 0.002A, and a maximum duty cycle of 80%.
Designed with advanced control loop architecture (D-CAP3™), it supports large bulk capacitors and small MLCCs without external compensation. The device includes integrated power MOSFETs with low resistance (2.9 mΩ and 1.2 mΩ) and offers features such as adjustable current limit, differential remote sense, power good indication, pre-bias start-up, and soft start.
The TPS548D22RVFR is housed in a 40-LQFN-CLIP package measuring 7 mm x 5 mm, suitable for surface mount applications. It operates within a junction temperature range of -40°C to 125°C.
