EVAL BOARD , 60W FLYBACK CONVERTER

60W wide input range flyback converter using HVLED001A quasi resonant flyback controller. It provides a stable and insulated 52V voltage bus suitable for secondary side circuitry (LED current generators) for a total output power of 60W, given a wide input voltage range. An auxiliary 15V output is also present to supply small circuitries absorbing a maximum current of 50mA. A very high power factor is obtained due to the features of the HVLED001A device. Input voltage variations, excessive input voltage (overvoltage from surges or bursts) or very low input voltages are handled through several HVLED001A protections, improving the reliability of the application. Output short circuit and overload protections with auto-restart are available for safe operation in lighting environments.
