STEVAL-ILL076V1 STMicroelectronics

S T E VA L - I L L 0 7 6 V 1 40 W European input-range ultra-slim flyback converter using the HVLED001 quasi resonant flyback controller Data brief Description The STEVAL-ILL076V1 product evaluation board implements an offline power converter based on a single-stage high-PF flyback topology using the HVLED001 controller. 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. Very high efficiency is obtained and a full set of protection features are implemented, including Features protection against output short-circuit and input Input voltage: V : 180 - 264 V , f: 45 - 66 IN RMS overvoltage. Hz Conducted EMI is pre-screened and clearance Output voltage: 56 V / 720 mA and creepage distances are within EN60950 High power factor, low THD safety standards. No-load: better than 400 mW 230 V IN Full load efficiency: better than 92% Power factor and THD measurements are Short-circuit protection with auto restart optimized to be higher than 0.95 and lower than EMI: pre-compliant with EN55022 (B) limits 10%, respectively, at full load. Dimensions: 183 mm x 28 mm, h 17 mm The main application for this converter is bus PCB: single-side 35 m, FR4, mixed power supply for an LED string driver providing 4 PTH/SMD kV of isolation.
