PHOTOFLASH CHARGER
Description
The ZXSC440 is a dedicated photoflash charger,charging an
80μF photoflash capacitor to 300V in 3.5 seconds from a 3V
supply.
Pin Assignments
(Top View)
The flyback conversion efficiency is typically 75%,much
higher than the commonly used discrete charging circuits.
The Charge pin enables the circuit to be initiated fromthe
camera's microprocessor, using negligible current when flash
is not being used.
The Ready pin signals the microprocessor when the flash is
charged and ready to be fired.
A small amount of hysteresis on the voltage feedback shuts
down the device as long as the capacitor remains fully
charged, again using negligible current.
