Preliminary RT9591 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 two AA batteries or a single 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.
