Product details

Step-down regulator for 4 A rails

The TPS62865RQYR is a synchronous buck regulator from Texas Instruments delivering up to 4 A continuous output from a 2.4 V to 5.5 V input rail. Switching at 2.4 MHz allows the use of small inductors and ceramic capacitors, shrinking the total solution footprint for space-constrained power supplies.

Parametric fit for industrial and telecom

The 9-VQFN-HR package (1.5 mm x 2.5 mm) with exposed thermal pad requires a solid ground-plane connection and adequate via array to keep junction temperature within limits at full 4 A load.

Frequently asked questions

Can TPS62865RQYR be used for 5V to 3.3V conversion?

Yes, with a 5 V input and the feedback resistors configured for 3.3 V output, the part operates within its 2.4 V to 5.5 V input range and delivers up to 4 A.
