STMicroelectronics offers a complete tool line, tailored to the STEVAL-ILL026V1 3 W NOT-ISOLATED OFFLINE LED DRIVER BASED ON VIPER22ASTR-E.

The progress made in the field of LEDs is visible on an almost day-by-day basis. Many high power LEDs are currently on the market, such as 0.7 A and 1 A devices. However, the most commonly used LEDs are those with a current of 0.350 A. The internal control circuit offers a large input voltage range on the VDD pin, accommodates changes in auxiliary supply voltage, and supports automatic burst mode in low load conditions. The board also features protections against overtemperature, overcurrent and overvoltage conditions.


  • Input voltage: 90 to 265 VRMS
  • Provides 350 mA constant current for LEDs
  • Capable of driving 3 x 1 W LEDs in series with high-precision constant current (± 5% tolerance)
  • Overtemperature protection
  • LED open circuit protection
  • LED short-circuit protection
  • 230 VAC input version with no electrolytic capacitor
  • EN55015 & EN6100-3-2 compliant
  • RoHS compliant
