LD7268 charger equivalent, photoflash capacitor charger.
z Adjustable charging current z Adjustable output voltage z Supports auto refresh z 2.8V~5V Lithium battery voltage range z Internal soft start z Tiny transformer z Totem.
the input current is usually limited at 500mA or 300mA. The LD7268 could easily meet either 500mA or 300mA applications.
The LD7268 is an ideal charge control IC for flash units with internal soft start, adjustable charging current and output voltage. It provides a proprietary constant current charging algorithm which charges photoflash capacitor quickly and efficientl.
