STMicroelectronics (Geneva, Switzerland) offers the STCF04 chip, an integrated camera flash and torch controller that raises the maximum power of an LED flash module to over 40 Watts. The 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 combines a supercapacitor, a discrete high-current MOSFET switch, and high-power white LEDs. Other features include: 100mA privacy indicator red LED output; 12 adjustment steps; and I2C bus with selectable address. The device is available in the 25-bump 3 × 3 mm TFBGA package.
