Description for the TPS54620

The TPS54620 in thermally enhanced 3.50 mm × 3.50 mm QFN package is a full featured 17-V,6-A, synchronous, step-down converter which is optimized for small designs through high efficiencyand integrating the high-side and low-side MOSFETs. Further space savings are achieved throughcurrent mode control, which reduces component count, and by selecting a high switching frequency,reducing the footprint of the inductor.

The output voltage start-up ramp is controlled by the SS/TR pin which allows operation aseither a stand-alone power supply or in tracking situations. Power sequencing is also possible bycorrectly configuring the enable and the open-drain power good pins.

Cycle-by-cycle current limiting on the high-side FET protects the device in overloadsituations and is enhanced by a low-side sourcing current limit which prevents current runaway.There is also a low-side sinking current limit that turns off the low-side MOSFET to preventexcessive reverse current. Thermal shutdown disables the part when die temperature exceeds thermalshutdown temperature.
