Product Summary
The LD7266EGDHW 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 to charge photoflash capacitor quickly and efficiently. The LD7266EGDHW could operate in constant charging current mode or the mode with lowering the charging current at lower battery voltage. As well, the built-in 40V power switch and IGBT driver can save the board space. The applications of the LD7266EGDHW are DSC Flash Unit and Cell Phone with Camera.
