The 11-VQFN-HR package (2x3 mm) keeps the footprint small for space-constrained power rails. Input range spans 3 V to 17 V, output is adjustable from 0.8 V up to 12 V. The integrated synchronous rectifier improves efficiency at low output voltages. Surface-mount mounting, tape-and-reel or cut-tape delivery. ROHS3 compliant. Sourced per RFQ against BOM quantity; no stock-holding claim.","metaTitle":"TPS621361RGXR – TI Buck Regulator, 4A, 1 MHz, Active","metaDescription":"Texas Instruments TPS621361RGXR step-down buck regulator, 4A output, 1 MHz switching, -40°C to 125°C, 11-VQFN-HR package.
