In January 2012, STMicroelectronics launched the STCF04, an integrated camera flash and torch controller.

Features and USP: The STCF04 raises the maximum power of an LED flash module from a few watts, which is typical of today’s designs, to over 40 watts, 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.

The STCF04 is used in a unique configuration combining a super-capacitor, a discrete high current MOSFET switch and high power white LEDs, and is ideal for use in emergency high intensity flashing lights as well as in camera and camera-phone applications.
