STMicroelectronics (referred to as ST) will allow for compact digital cameras and smart phones to meet the user to improve the built-in flash output power requirements, while supporting the more advanced user control.
STMicroelectronics new chip STCF04 of a built-in flash / best LED flashlight, dual-mode camera flash controllers, LED flash module maximum power from today, generally a few watts of power designed to improve more than 40W, the issue of outdoor security floodlights level brightness. The new product offers more flash and flashlight brightness control feature, the flash mode has 8 user-selectable brightness, LED flashlight mode 12 user-selectable brightness, and a light sensor input. The controller chip built-in flash and torch safety timer, temperature sensor and short circuit protection.
STCF04 STMicroelectronics unique architectural design, integration of a super capacitor, a high-current MOSFET switching of discrete devices and multi-branch high-power white LED light, is the ideal choice for high brightness emergency flash and the camera and camera phone flash.
MOSFET discrete devices STCF04 of power than similar products key, because the other brands of controllers only integration of a power MOSFET. The new product design alternative to traditional high-power xenon flash (to xenon flash) with LED flash, to meet the requirements of todays high-pixel camera sensor, the higher light, but also has the advantages of compact design and simple.
STMicroelectronics has begun to the two major partners Murata (of MURATA) and OSRAM provides STCF04 sample. Murata Manufacturing Co., a market leader in the super capacitor manufacturers, Osram is the worlds leading supplier of flash module of the smartphone, the two companies have begun to show the latest products using the chip.
STCF04 main features:
Maximum flash power> 40W
Torch-mode current (the torch current): 1 x 320mA
100mA Red LED privacy indicator light output; 12 adjustment
Address optional I2C bus
Temperature sensing, short circuit shut down, overvoltage protection and security features of flash / flashlight mode timer
STCF04 TFBGA package 3 x 3mm, 25-ball has been available for sampling. Is expected to begin volume production in the first quarter of 2012.
More LED items: 12 volt LED lights and others.
