Allegro MicroSystems has announced its latest generation of advanced LED backlight drivers, the A8060x family. The device family is designed with an innovative and patented Pre-Emptive Boost (PEB) control, eliminating noise that is typically audible. PEB control in the A8060x family substantially reduces Vout ripple and eliminates the common problem of audible noise from ceramic output capacitors during PWM dimming, while also requiring less output capacitance overall.
The emerging trend of smart lighting and Internet of Things, requires a new generation of LED drivers. Infineon Technologies has introduced a new member of its XDP LED series, the XDPL8221 for cost-effective dual-stage drivers with advanced features. This device combines a quasi-resonant PFC and a quasi-resonant flyback controller with primary side regulation together with a communication interface.

The intensity and phase modulators from LASER COMPONENTS operate from low frequencies up to 40Gbps/40GHz and for a broad range of wavelength windows including 800, 1,060, 1,300, 1,550nm and two microns. Matched with the family of iXblue RF drivers, these modulators serve all applications, from laboratory experiments to demanding industrial systems.
An ultrafast laser driver with a high-power, multi-channel Surface Mount (SMT) laser for LiDAR (Light detection and ranging) systems has been announced by Osram Opto Semiconductors. Osram and GaN Systems partnered to develop the breakthrough in laser driver technology that enables longer range and higher resolution LiDAR architectures.
LED lighting is taking over on the roads. It enables new design trends in cars, such as flexible styling and animation, and increases safety in traffic. If LEDs fail, this affects the reliability of the light. With LITIX Basic+, a new LED driver family , Infineon is launching the most flexible single LED short circuit diagnostic feature available on the market at electronica 2018.
GlacialPower new GP-LE150N DC LED driver suitable for LED strip light, LED signage and moving sign applications. The new series are available in 12V DC output rated power of 120 W, and 24V DC output rated power of 150 W. The GP-LE150N is suitable for exterior or interior usage, with a fully isolated plastic case and isolated cable that is IP67 rated for environmental protection from rain, water and dust.
This reference design is a dual string LED driver that implements an operational amplifier based circuit which balances the current in two LED rings. The operational amplifier circuit senses current in a reference string and uses feedback from a mirrored string to bias a MOSFET that egulates the current between the strings.
