Product Overview

The TPS54620RGYR is a synchronous Step-down Converter optimized for small designs through high efficiency and integrating the high-side and low-side MOSFETs. Further space savings are achieved through current-mode control, which reduces component count and by selecting a high switching frequency, reducing the inductor's footprint. The output voltage startup ramp is controlled by the SS/TR pin which allows operation as either a stand-alone power supply or in tracking situations. Power sequencing is also possible by correctly configuring the enable and the open drain power good pins. Cycle-by-cycle current limiting on the high-side FET protects the device in overload situations and is enhanced by a low-side sourcing current limit which prevents current runaway. There is also a low-side sinking current limit which turns off the low-side MOSFET to prevent excessive reverse current. Thermal shutdown disables the part when die temperature exceeds thermal shutdown temperature.
