General Description

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 efficiently. Besides, the built-in totem pole IGBT driver can drive IGBT quickly and save board space.

For phone flash applications, the input current is usually limited at 500mA or 300mA. The LD7268 could easily meet either 500mA or 300mA applications.

The LD7268 is available in a space-saving MSOP-10 package and is ideal for phone flash or DSC flash unit.
