LD7261 Datasheet | Leadtrend

Photoflash Capacitor Charger 3/21/2005 REV: 01 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. The LD7261 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 LD7261 is available in a space-saving MSOP-10 package and is ideal for DSC flash unit.
