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.","metaTitle":"TPS62865RQYR - Texas Instruments Buck Regulator 4A 2.4MHz","metaDescription":"TPS62865RQYR step-down buck regulator from TI, 4A output, 2.4MHz switching, adjustable output from 0.8V to 5.5V.
