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 […]

Tiny LED drivers offer up to 110 W output with no heatsinks
Power Integrations announced new high-power-density members of its LYTSwitch-6 family of safety-isolated LED-driver ICs for smart lighting applications. The new ICs with PowiGaN technology enable designs that deliver up to 110 W with 94% conversion efficiency using a simple, flexible flyback topology. The high efficiency of the new LYTSwitch-6 ICs eliminates the need for heatsinks – […]
LED drivers streamline interior and exterior lighting
Diodes Incorporated introduced two automotive LED drivers that combine robust performance, simplified design, and flexibility to address internal and external lighting applications, such as fog lamps, position lamps, rear lamps, and door lamps. The AL8860Q and AL8861Q have a wide-operating voltage range from 4.5V to 40V to withstand load-dump events and operate correctly at low-cranking […]
Buck-boost LED drivers provide up to 90% efficiency
Designers of high-performance automotive lighting applications now have a simpler, more efficient method for driving high-brightness LEDs (HBLEDs) with the MAX25610A and MAX25610BLED drivers from Maxim Integrated Products, Inc. The synchronous buck, buck-boost LED drivers/DC-DC converters offer a complete solution that features industry-leading EMI performance, without compromising on efficiency and size. These ICs drive up to eight HBLEDs […]
