LD7261A Datasheet | Leadtrend

3/10/2005 Photoflash Capacitor Charger for DSC Target Spec. REV: 00 General Description The LD7261A 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. The LD7261A is specially designed for automatically and linearly lowering the charging current at lower battery voltage. As well, a built-in totem pole IGBT driver can drive IGBT quickly and save the board space. The LD7261A is available in a space-saving MSOP-10 package and is ideal for DSC flash unit.
