Distortion-Cancelling High-Voltage LED Driver from STMicroelectronics Future-Proofs Energy-Saving Lighting


Geneva, Switzerland – WEBWIRE

Ideal for Smart Industry, Smart City, and Smart Home lighting applications


Geneva, September 16, 2019 -- Featuring a novel distortion-cancelling input-current shaping (ICS) circuit, the HVLED007 AC/DC LED driver from STMicroelectronics enables energy-saving solid-state luminaires to comply with increasingly stringent lighting regulations.

The HVLED007 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 designersí needs for a single control IC to address multiple medium- and high-power LED-lighting applications up to 80W.

The HVLED007 completes STís HVLED family of digital ICs for driving LEDs directly from the rectified mains. With their advanced integration and features that support economical primary-side regulation, HVLED drivers enable lower bill-of-materials costs and compact circuit size while enhancing system reliability and lighting performance.

The electrical parameters of the HVLED007 are specified down to -40įC, 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.

The HVLED007 is in production now in the industry-standard SO8 small-outline package, from $0.36 for orders of 1000 pieces.
