Smart Photoflash Capacitor Charger with IGBT Driver

General Description

The RT9591 is a highly integrated photoflash charging

solution in digital and film cameras. It is targeted for

applications that use either

lithium-ion battery.

The RT9591 integrates a constant current controller for

charging high voltage photoflash capacitor quickly and

efficiently, an IGBT driver for igniting flash tube, and a

voltage detector. Only a few external components are

used to reduce PCB space and cost.

RT9591 is available in VQFN-16L 3x3 package.
