  • The EVALHVLED805 is a demonstration board equipped with the new HVLED805 PWM current mode LED driver and is designed for European mains. It can control, with very good accuracy, from 1 to 3 LEDs having a nominal current of 350 mA. The HVLED805 has integrated high voltage startup and an 800 V power MOSFET. The high MOSFET's breakdown voltage allows very robust and reliable applications and reduces the size of the snubber and the relative power dissipation. Its accurate primary-current control eliminates the need of the optocoupler which impacts the cost, the compactness and the lifetime of the application while still maintaining a very good LED accuracy (below 5 %). Moreover, this converter, specifically designed for quasi-resonant (QR) flyback converters, enables very low turn-on losses and EMI emissions.

    主要特性

    • Input voltage range (VIN): 185 - 265 VAC
    • Main frequency (fL): 50 - 60 Hz
    • Maximum (rated) output power: 4.2 W
    • Output: IOUT= 350 mA ± 5%
      • Over voltage = 12 V max
      • Current ripple < 10% IOUT
    • Minimum switching frequency in normal mode: 70 kHz
    • Target average efficiency (from 1 to 3 LEDs) > 70 %
    • Maximum input power in no-load < 100 mW
