VINx Capacitor Selection
According to the USB 2.0 specification, USB peripherals have a
detectable change in capacitance on VBUS when they are attached.
The peripheral device VBUS bypass capacitance must be at least
1 μF but not larger than 10 μF. The combined capacitance for
the VINx and CFILT pins must not exceed 10 μF at any tempera-
ture or dc bias condition. Suggestions for a VINx capacitor is
given in Table 32.
CFILT Capacitor Selection
CFILT pin serves the
converter input capacitor. Maximum input capacitor current
is calculated using the following equation:
To minimize supply noise, place the input capacitor as close as
possible to the CFILT pin of the charger. As with the output
capacitor, a low ESR capacitor is recommended.
The effective capacitance needed for stability, which includes
temperature and dc bias effects, is a minimum of 2 μF and a
maximum of 5 μF. A list of suggested capacitors is shown in
Table 31.
