VINx Capacitor Selection

According to the USB 2.0 specification, USB peripherals have a

detectable change in capacitance on VBUS when they are attached

to a USB port. The peripheral device VBUS bypass capacitance

must be at least 1 µF but not larger than 10 µF.

The VINx input of the ADP5063 is tolerant of voltages as high

as 20 V; however, if an application requires exposing the VINx

input to voltages of up to 20 V, the voltage range of the capacitor

must also be above 20 V. Suggestions for a VINx capacitor are

given in Table 36.

When using ceramic capacitors, a higher voltage range is usually

achieved by selecting a component with larger physical dimensions.

In applications where lower than 20 V at VINx input voltages can

be guaranteed, smaller output capacitors can be used accordingly.
