Preliminary Datasheet, Confidential - D e ta i l e d D e s c r i p t i o n

8 Detailed Description

The AS3636 is a highly integrated photoflash charger with build in IGBT driver, inductive DCDC boost autofocus/video

LED driver, an indicator LED driver and it includes system level ESD protection and a breakable fuse. The integrated

fuse will be blown if there is short circuitry in the module

Note: The AS3636 uses a WL-CSP (wafer level chip scale package) to optimize the PCB area required and minimize

the module size. Therefore the actual DIE is visible (and it is not molded in plastic as for other packages like

QFN or DFN) and the AS3636 is sensitive to external light. It has to be protected from direct light from the

Xenon tube.
