Description
The STEVAL-ILL069V2 supplies a stable and
insulated 48 V voltage bus suitable for secondary
side circuitry (e.g., LED current generators) for a
total output power of 35 W when a wide range of
input voltages is applied at its input. An auxiliary
16 V output is also present to supply small
circuits which absorb a maximum current of 20
mA.
A very high power factor is obtained thanks to the
features of the HVLED001A. Input voltage
variations, excessive input voltage (surge or burst
overvoltage) or very low input voltages are
managed by some of the protections of the
HVLED001A, improving the reliability of the
application.
The efficiency of the application is very high even
at very low load thanks to the improved
frequency fold-back feature that also reduces the
output voltage ripple at light load.
Output short circuit and overload protections are
auto-restart for safe operation in lighting
environments.
