STEVAL-ILL074V2

STEVAL-ILL074V2 60 W wide input range flyback converter using HVLED001A controller in FOT mode Data brief Description The STEVAL-ILL074V2 provides a stable, 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 range of 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 (overvoltages like surges or bursts) and very low input voltages are managed by the HVLED001A protections, improving the reliability of the application. Features         Input voltage: Vin = 90 - 277 Vrms, f = 45-66 Hz Output voltage: 52 V / 1.2 A High power factor, low THD Full load efficiency: above 90% Short circuit protection Safety: compliant with EN60065 PCB board: 165 mm x 50 mm double-sided PCB RoHS compliant February 2017 Output short circuit and overload protections are available with auto-restart for safe operation in lighting environments.
