STMicroelectronics (NYSE: STM), a semiconductor leader serving customers across the spectrum of electronics applications, has introduced the HVLED007 AC/DC LED driver with a new distortion-cancelling input-current shaping (ICS) circuit that could enable energy-saving solid-state lighting that meets increasingly stringent lighting regulations.

The HVLED007 implements peak current-mode PFC control optimized for isolated and high-power-factor quasi-resonant flyback converters.

ICS effectively guarantees a sinusoidal input waveform with very low total harmonic distortion (THD) over the full load and input voltage range, where THD is less than 5% at full load.

The HVLED007 enables designers to address medium- and high-power multi-LED lighting applications up to 80 W with a single control IC, with near-constant power factor and peak energy efficiency of over 90%.

The HVLED007 belongs to ST's family of HVLED digital ICs that drive LEDs directly from a rectified mains supply. HVLED drivers feature advanced integrated performance and features that support economical primary-side regulation, reducing material costs and circuit size while improving system stability and lighting performance.

The electrical parameters of the HVLED007 are specified for operation down to -40°C, allowing it to be used in outdoor lighting, including streetlights, in addition to indoor lighting applications.

The totem-pole outputs can source and sink 600mA and 800mA respectively, making them suitable for lighting applications as well as EN61000-3-2 compliant switch-mode power supplies up to 100W. Protection features include short-circuit, overload and overvoltage protection.
