ZXSC440 - PHOTOFLASH CHARGER

The ZXSC440 is a dedicated photoflash charger, charging an 80␮F photoflash capacitor to 300V in 3.5 seconds from a 3V supply.

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 from the
