LD7270 6/18/2010 Smart Photoflash Capacitor Charger with Integrated MOS REV：03 General Description The LD7270 is an ideal charge control IC for flash units, featuring internal soft start, adjustable charging current and output voltage. It provides a charging algorithm to speed up the charging with higher efficiency. The LD7270 can operate in desired constant peak current mode through adjusting RI between ISET pin and GND. As well, LD7270 uses separate source and sink pin of IGBT driver, which enables the users to easily meet different IGBT application requirements. The LD7270 is available in a space-saving WDFN-10L 3x3 package and is ideal for DSC flash unit. g Patented Features • 1.
