LD7266A 3/1/2007 Photoflash Capacitor Charger with Integrated MOS REV: 00 General Description The LD7266A 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 LD7266A could operate in constant charging current mode or the mode with lowering the charging current at lower battery voltage. As well, the built-in 45V power switch and IGBT driver can save the board space. The LD7266A is available in a space-saving MSOP10 or DFN-10 package and is ideal for DSC flash unit. Features • Adjustable Charging Current and Output Voltage • 1.
