... NCP5080 Xenon Photoflash Capacitor Charge with Photo Sense Interface The NCP5080 product is a high voltage boost driver dedicated to the Xenon power flashes. The built-in DC/DC converter is based on a flyback structure with an external transformer to adapt any range of high voltage demand. The external feedback network makes it possible to dynamically adjust of the output voltage ...
