STEVAL-ILL076V2 18 W wide input range ultra slim flyback converter using HVLED001A quasi resonant flyback controller and STD8N80K5 Data brief Description This board implements an offline power converter based on a single stage high-PF flyback topology using the HVLED001A controller. A very slim form factor is achieved with innovative magnetic componentry. The output voltage is controlled by the primary side, thus reducing the need for costly optocouplers. The HVLED001A PSR precision and the innovative structure of the transformer makes for highly accurate output voltage regulation against load and line changes. Features Input voltage: Vin: 90 - 264 Vrms, f: 45 - 66 Hz Output power: 18 W at wide input range 40 W at European input range Output voltage: 56 V 5 % High power factor, low THD No-load: better than 400 mW at 230 Vin Full load efficiency: greater than 92 % Short circuit protection with auto restart EMI: pre-compliant with EN55022 (B) limits Safety: complies with EN60950 Dimensions: 183 mm x 28 mm x 17 mm PCB: single sided, 35 m, FR4, mixed PTH/SMD RoHS compliant September 2016 A very high efficiency is obtained and a full set of protections including output short circuit and input overvoltage is included. Conducted EMI is pre-screened and clearances and creepage distances adhere to EN60950 safety requirements. Power factor and THD are optimized to be respectively higher than 0.95 and lower than 10% at full load over the entire input voltage range. The main application for this converter is for bus power supplies in a LED string driver providing 4 kV isolation.
