  • The STEVAL–LLL003V1 evaluation board is a constant current LED driver, based on non–isolated buck topology using VIPer0P.

    The board delivers 130 mA ± 2.5% at an output load of 15 – 21 white LEDs.
    The buck topology ensures a minimum number of components as well as higher efficiency when operating at high output voltage (60 V and above).
    The application core is the new VIPer0P offline high voltage converter which smartly integrates an 800 V avalanche rugged power MOSFET with current-mode control.
    Thanks to the embedded E/A (EAGND) floating GND, the direct current regulation can be applied to the buck converter, improving the LED current accuracy.

    Key Features

    • Non-isolated buck topology
    • Two input voltage ranges:
      • US range: 85-135 VAC (jumper J2 - closed, voltage doubler)
      • EU range: 175-285 VAC (jumper J2 - open, bridge rectifier)
    • 130 mA ±2.5% output constant current (15-21 white LEDs connected)
    • 60 kHz fixed frequency operation
    • ≅89% efficiency at maximum load
    • Protections:
      • open/no-load circuit protection
      • short/overload circuit protection
      • thermal shutdown
    • Soft start for improved system reliability
    • Meets IEC55022 Class B conducted EMI even with reduced EMI filter, thanks to the frequency jittering feature
    • Meets IEC61000-4-2(ESD), IEC61000-4-4 (Burst) and IEC61000-4-5 (Surge)
    • RoHS compliant
