Product details

6A fixed-output buck in a PowerTSSOP

The TPS54612PWPR is a Texas Instruments SWIFT™ series step-down (buck) regulator delivering a fixed 1.2V output at up to 6A continuous. 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.

Frequently asked questions

How does TPS54612PWPR compare to TPS65261RHBT?

TPS65261RHBT is a triple-output buck (3× 3A) with adjustable outputs and a 2 MHz switching frequency, while TPS54612PWPR is a single 6A fixed-output buck at 350/550 kHz. They are not pin-compatible — the TPS65261RHBT comes in a 40-QFN package. The choice depends on whether your BOM needs one high-current rail or three lower-current rails.
