AT1453照相机闪光灯电容充电器控制器芯片Pdf资料

应用功能： 照相机闪光灯电容充电器控制器芯片 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 resistor to change the switching duty and use of transformer to control the input current.
