TPS65281-1RGVR Description

Short technical summary and product information.

The Texas Instruments TPS65281-1RGVR is an integrated power distribution switch and buck converter designed for versatile power management applications. It operates within a wide input voltage range of 4.5V to 18V, providing a maximum continuous output current of 3A.

 

Key electrical features include an adjustable current limit from 75mA to 2.7A with ±6% accuracy at 1.7A, a feedback reference voltage of 0.8V ±1%, and a switching frequency adjustable from 300kHz to 1.4MHz. The device incorporates protection mechanisms such as over-current latch-off (or auto-recovery for TPS65281-1), reverse input-output voltage protection, over-temperature protection, and output over-voltage protection.

 

This component is housed in a 16-VQFN (4x4 mm) package, suitable for surface mounting. It offers features like adjustable soft-start, power good indication, and synchronous rectification, making it a robust solution for various power supply designs.
