A8438 Photoflash Capacitor Charger With IGBT Driver

The A8438 is a highly integrated IC that charges photoflash capacitors for digital and film cameras. It also features an integrated IGBT driver that facilitates the Flash discharge function and saves board space.
To charge the photoflash capacitor, the A8438 integrates a 40 V, DMOS Switch that drives the transformer in a flyback topology, allowing optimized design with tight coupling and high efficiency. A proprietary control scheme optimizes the capacitor charging time. Low quiescent current and low shutdown current further improve system efficiency and extend battery life.
