(2) Theoretically there is no upper limit to the V
AC supply voltage because this voltage is dropped across the C
S capacitor; see the
Calculating the Cap-Drop Capacitor section for details.
(3) The voltage ratings for the cap-drop capacitor C
S and the surge resistor R
S must be able to handle the peak V
AC supply voltage; see the
Typical Application section for details.
(4) The surge resistor R
S is required to limit the inrush current into or out off either AC+ or AC– pins during hot-plug or surge current events; see the
Calculating the Surge Resistor section for details.
(5) Only available for devices with ≤ 3.3-V output voltage options.
(6) DC-supply mode is also availabe for 3.6-V devices but with a minmum required VSCIN supply voltage of 18 V.
(7) A 16 V or higher voltage rating is recommended for the CSC1 capacitor, and a 10 V or higher voltage rating is recommeded for the CSC2 capacitor.
