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.
