Austria microelectronics can output 1A current white LED flash driver IC

Austria Microelectronics Corporation (Austriamicrosystems) listed on the output 1A current white LED flash drive IC "AS3645". The company said, compared with the existing equivalent products, new products output current should be higher than 25%". Mainly for digital cameras, digital cameras and PDA, etc..

This is a fixed switching frequency of 2MHz boost DC-D converter circuit of the white LED flash driver IC. Switch element integration. Can drive 1 white LED or series of 2 white LED. Driven by 1 white LED, the maximum supply current of 720mA; when driving the 2 white LED, respectively, the maximum supply of 500mA, the total current of 1A. It has the function of preventing overtime power supply to the LED, the over voltage / low voltage protection function, the overheat protection function and the LED short circuit protection function. In addition, there is also a circuit that can drive the indicator LED. Supply current and supply time to LED can be set by I2C bus.

The working temperature range of 30 ~ 85 C. 12 terminal WLCSP package with packaging area of 2mm * 1.6mm. 1000 bulk purchase price of $0.90.
