AS3635 Xenon Flash Driver

The AS3635 is a highly integrated photoflash charger with build in IGBT driver. A build in 5V charge-pump guaranties constant IGBT drive at any battery voltage. The build in timer turns off the charge-pump 20 seconds after charging. In circuit fuse trimming allows to set the voltage on the photoflas.
