The A8426 is a highly integrated IC that rapidly charges photoflash capacitors for SLR cameras, digital cameras, and camcorders with integrated digital cameras. A flexible IGBT driver is integrated to save board space.
The A8426 integrates a 3.2 A-capable, 55 V-rated DMOS switch that drives the transformer in flyback configuration, allowing optimized design with tight coupling and high efficiency. The peak switch current is user-adjustable between 1 and 3.2 A, using a resistor to ground. A proprietary control scheme optimizes the capacitor charging time. Low quiescent current and low-power Standby mode current further improve system efficiency and extend battery life.
The A8426 is available in a 16-contact 3 mm × 3 mm TQFN package with exposed pad for enhanced thermal performance. This small, very thin profile (0.75 mm nominal overall height) package is ideal for space-constrained applications. It is lead (Pb) free, with 100% matte-tin leadframe plating.
This device is no longer in production. The device should not be purchased for new design applications. Samples are no longer available. Date of status change: June 30, 2017
