AT1452 Description

The AT1452 is a charger control IC for Photoflash capacitor with soft start function, adjustable maximum duty cycle, auto-refresh and autodischarge (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 resistor to change the switching duty and use of transformer to control the input current.
