Input range spans 3V to 6V, making it a direct fit for 5V or 3.3V intermediate rails in a point-of-load design. ## Switching frequency and thermal range Switching frequency is pin-strapped to either 350 kHz or 550 kHz — the lower setting reduces switching losses at light load, the higher one shrinks the inductor footprint. Integrated synchronous rectifier eliminates the external Schottky diode that a non-synchronous buck would need, saving a component and reducing the thermal load on the PCB. ## 28-HTSSOP package — what the board needs The 28-PowerTSSOP (HTSSOP) has an exposed thermal pad on the bottom. The 4.40 mm body width means the pad sits on a standard 0.65 mm pitch leadframe; layout guidelines from TI recommend a 2.8×4.4 mm pad area with at least four vias into the ground plane. RoHS3 compliant, no exemptions listed.","metaTitle":"TI TPS54612PWPR SWIFT Buck Regulator, 6A, 28-HTSSOP","metaDescription":"Texas Instruments TPS54612PWPR SWIFT step-down regulator, 6A output, 3V to 6V input, 350/550kHz switching, -40 to 125°C.
