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.
