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 drive... |
