A8735 Ultra Small Mobile Phone Xenon Photoflash Capacitor Charger

The Allegro® A8735 is a Xenon photoflash charger IC designed to meet the needs of ultra low power, small form factor cameras, particularly camera phones. By using primary-side voltage sensing, the need for a secondary-side resistive voltage divider is eliminated. This has the additional benefit of r.

A8735 Features
