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.
