TPS54062DGKR .

The TPS54062DGKR is a 60V 0.5A Synchronous Step-down Converter with integrated high-side and low-side MOSFETs. Current mode control provides simple external compensation and flexible component selection. The non-switching supply current is 89µA. Using the enable pin, shutdown supply current is reduced to 1.7µA. Under-voltage lockout is internally set at 4.5V, but can be increased using the accurate enable pin threshold. The output voltage start-up ramp is controlled by the internal slow-start time. Adjustable switching frequency range allows efficiency and external component size to be optimized. Frequency foldback and thermal shutdown protects the part during an overload condition.
