Description

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.
