STCF04 high-power LED SuperCap driver with I²C interface

The STCF04 is an integrated camera flash and torch controller that raises the maximum power of an LED flash module from a few watts, typical of today’s designs, to over 40 W, producing the brightness equivalent to an outdoor security floodlight. The new device also provides extra flash and torch brightness controls, with eight user-selectable levels for the flash and 12 for the torch, as well as a light-sensor input.  Flash and torch safety timers, temperature sensing and short-circuit protection features are also built in.
