HVLED805 LED Driver Development Kit
Specifications EU RoHS Not Compliant Type Development Kit Supported Device HVLED805 Product Category Optoelectronics Tools Development Kits and Tool Detail Description EVALHVLED805 is HVLED805 evaluation board: insulated LED driver with primary current controlEVALHVLED805. 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. Features 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 Additional Information Product Specifications BOM for EVALHVLED805 board
