The HVLED007 LED driver implements a peak current mode PFC control optimized for isolated high-power-factor quasi-resonant flyback converters. The ICS ensures an effectively sinusoidal input waveform with very low total harmonic distortion (THD) over the full load and input-voltage range; THD is below 5% at full load. With near-unity power-factor capability and maximum energy efficiency over 90%, the HVLED007 meets designers’ needs for a single control IC to address multiple medium- and high-power LED-lighting applications up to 80W.
The electrical parameters of the HVLED007 are specified down to -40°C, allowing use in outdoor lighting including street-lighting as well as indoor applications. The totem-pole output stage can source and sink 600mA and 800mA respectively, enabling use in EN61000-3-2 compliant switched-mode power supplies up to 100W in addition to lighting applications. Protection features including short-circuit, overload, and over-voltage protection are built-in.
