Description
The A8837 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 A8837 and starts the charging of the output
capacitor. When the designated output voltage is reached, the A8837 stops the
charging until the CHARGE pin is toggled again. The DONE pin is an open-drain
indicator of when the designated output voltage is reached.
