9 Power Supply Recommendations

The device has one power supply input, IN, which is the chip supply. It is connected to the OUT pin via a power integrated MOSFET and in the case of the TPS25820 it also is MUXed either to CC1 or CC2 pin in the Type-C receptacle depending on cable plug polarity.

USB Specification Revision 2.0 and 3.1 requires VBUS voltage at the connector be between 4.75 V to 5.5 V. Depending on layout and routing from supply to the connector, the voltage droop on VBUS has to be tightly controlled especially when providing 1.5 A. Locate the input supply close to the device. For all applications, a ceramic bypass capacitor between OUT and GND less than 10 μF is recommended and should be placed as close to the Type-C connector and device as possible for local noise decoupling. The power supply should be rated higher than the current limit set to avoid voltage droops during overcurrent and short-circuit conditions. Also see Input and Output Capacitance Considerations on chip by-passing considerations.
