The STEVAL-ILL074V1 provides a stable and insulated 52 V voltage bus suitable for secondary side circuitry (e.g., LED current generators), for a total output power of 60 W, given a wide input voltage range. An auxiliary 15 V output is also present to supply small circuitries absorbing a maximum current of 50 mA.

A very high power factor is obtained thanks 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.
