TPS54622, The equipment adopts thermal enhanced 3.5mm 3.5mm VQFN package, is a fully functional 17V 6A synchronous step-down converter; the device has high efficiency and integrated high side and low side MOSFET, optimized to achieve small design. Current mode control, greatly reducing the number of components, while reducing the size of the inductor by selecting a high switching frequency, thus further saving space.
The output voltage start ramp is controlled by the SS / TR pin, which supports both independent power operation and tracking mode. In addition, the correct configuration of the enabling and open leakage power supply good pin can also achieve the power supply sequence.
