2
Positive supply voltage input - connect to supply and make a short connection
to input capacitor C VIN and to coil L DCDC
2
Digital input with pulldown to control strobe time for flash function
Function 1: Connect to RF power amplifier enable signal - reduces currents
during flash to avoid a system shutdown due to parallel operation of the RF PA
and the flash driver
