General Description
The LD7261 is an ideal charge control IC for flash units with internal soft start, adjustable charging current and output voltage. It provides a proprietary charging algorithm, which charges photoflash capacitor quickly and efficiently. As well, a built-in totem pole IGBT driver can drive IGBT quickly and save the board space.
The LD7261 is available in a space-saving MSOP-10 package and is ideal for DSC flash unit.
