Средства разработки схем светодиодного освещения STEVAL-ILL074V2

Оценочная плата , обратноходовой преобразователь 60Вт, контроллер HVLED001A, режим FOT

The STEVAL-ILL074V2 from STMicroelectronics is a 60W wide input range flyback converter using HVLED001A controller in FOT mode. It provides a stable, insulated 52V voltage bus suitable for secondary side circuitry (e.g. LED current generators), for a total output power of 60W given a wide range of 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 by features of the HVLED001A device. Input voltage variations, excessive input voltage (overvoltages like surges or bursts) and very low input voltages are managed by the HVLED001A protections, improving the reliability of the application. Output short circuit and overload protections are available with auto-restart for safe operation in lighting environments.
