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 350mA.
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 quasiresonant (QR) flyback converters, enables very low turn-on losses and EMI emissions.
Maximum (rated) output power: 4.2 W
Output: IOUT = 350 mA ± 5%
– Over voltage = 12 V max
– Current ripple less than 10% IOUT
Maximum input power in no-load less than 100 mW
