General Description

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 reducing leakage currents on the secondary side of the transformer.
