General Description
The AT1452 is a charger control IC for Photoflash
capacitor with soft start function, adjustable
maximum duty cycle, auto-refresh 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 resistor to change the switching duty
and use of transformer to control the input current.
Automatic refresh allows the capacitor to remain
charged while output voltage dropped 10%. A
logic high on the CHARGE pin initiates charging,
while the READY pin signals that the capacitor is
fully charged. It is ideal for DSC flash unit.
