DESCRIPTION

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 camera's microprocessor, using negligible current

when flash is not being used.

FEATURES

• Charges a 80 F photoflash capacitor to 300V in

3.5 seconds from 3V

• Charges various value photoflash capacitors

• Over 75% flyback efficiency

• Charge and Ready pins

• Consumes only 4.5 A when not charging

• Small MSOP8 low profile package

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.

APPLICATIONS

• Digital camera flash unit

• Film camera flash unit
