The STEVAL-ILL069V2 is intended to provide a stable and insulated 48V voltage bussuitable to supply secondary side circuitry (e.g. LED current generators) for a total outputpower of 35W when a wide range of input voltages is applied at its input. An auxiliary 14Voutput is also present to supply small circuitries absorbing a maximum current of 20mA.A very high power factor is obtained thanks to HVLED001A features. Input voltagevariations, excessive input voltage (overvoltage like Surge or bursts) or very low inputvoltages are managed by some of the HVLED001A’s protections, improving the reliability ofthe application.Output short circuit and overload protections are autorestart for a safe operation in lightingenvironment.
