Description
The A8439 is a highly integrated IC that charges photoflash capacitors for
digital and film cameras. An integrated MOSFET switch drives the transformer
in a flyback topology. It also features an integrated IGBT driver that
facilitates the flash discharge function and saves board space.
The CHARGE pin enables the A8439 and starts the charging of the output
capacitor. When the designated output voltage is reached, the A8439 stops the
charging until the CHARGE pin is toggled again, or when output voltage falls
below 90% of the designated value. Pulling the CHARGE pin low stops the
charging. The DONE pin is an open-drain indicator of when the designated
output voltage is reached.
