AT1453 - Photoflash Capacitor Charger

The AT1453 is a charger control IC for Photoflash capacitor with soft start function, adjustable maximum duty cycle and auto-discharge (soft start capacitor) circuit. Adjustable soft start is programmed with an external capacitor on SS pin. The control technique allows for the use of external resist.
