STEVAL-ILL076V1

STEVAL-ILL076V1 40 W European input-range ultra-slim flyback converter using the HVLED001 quasi resonant flyback controller Data brief Description ) s t( The STEVAL-ILL076V1 product evaluation board implements an offline power converter based on a single-stage high-PF flyback topology using the HVLED001 controller. c u d o r P A very slim form factor is achieved using innovative magnetic parts. Output voltage is controlled by the primary side, reducing the need for costly opto-couplers. The precision of the HVLED001's PSR feature together with the innovative structure of the transformer make output voltage regulation very accurate against load and line changes. e t le o s b Features          Input voltage: VIN: 180 - 264 VRMS, f: 45 - 66 Hz Output voltage: 56 V / 720 mA High power factor, low THD No-load: better than 400 mW @ 230 VIN Full load efficiency: better than 92% Short-circuit protection with auto restart EMI: pre-compliant with EN55022 (B) limits Dimensions: 183 mm x 28 mm, h 17 mm PCB: single-side 35 µm, FR4, mixed PTH/SMD RoHS compliant c u d e t le so Ob  ) s t( -O September 2015 o r P Very high efficiency is obtained and a full set of protection features are implemented, including protection against output short-circuit and input overvoltage. Conducted EMI is pre-screened and clearance and creepage distances are within EN60950 safety standards. Power factor and THD measurements are optimized to be higher than 0.95 and lower than 10%, respectively, at full load. The main application for this converter is bus power supply for an LED string driver providing 4 kV of isolation.
