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.
