Описание
EVLHV101SSR50W board contains HVLED101 quasi resonant HPF flyback controller with secondary side regulation. It is intended to provide a stable and insulated 60V voltage for a maximum power of 50W. It can be used as a standalone power supply or as a front end stage in a dimmable (or non-dimmable) off line LED driver. A very high power factor, low THD and low BOM cost are obtained from this demonstration board due to the features of the HVLED101, which adopts frequency foldback with valley locking operation to reduce the switching losses and minimize acoustic noise. Extremely low input power is obtained at no-load. Input voltage variations, excessive input voltage (overvoltage like surges or bursts) and insufficient input voltage are managed by the HVLED101 protections, which improve the reliability of the application. Output short-circuit and overload protection with auto restart behaviour is implemented.
• Input voltage range from Vin 90 - 265Vrms(f: 45-66Hz), output voltage of 60V / 833mA
• High power factor, low THD
• Efficiency > 50% in stand-by (Pout = 240mW)
• 4 points (25%, 50%, 75%, 100% load) average efficiency > 91%
• Frequency foldback with valley locking for noise-free operation
• Open load voltage limiting (< 65V)
• NTC overtemperature protection for switching MOSFET
• Safety in accordance to EN60065 standard
• EMI in accordance to EN55022 - conducted emissions
