Here is a look back of Allegro’s A8515, a wide input voltage range, high efficiency fault tolerant white LED driver. The device was made available in the market since 2010. It features multiple output ...
Recent breakthroughs in LED technology have enabled LEDs with a broad spectrum of light output to be produced and not just the traditional red and green derivatives. Hence the sheer numbers of LEDs ...
Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate in ...
High power LED lighting is harder than it looks. Power, dimming, control, and communication collide in one design.
Toshiba has a voltage driven photo relay with a tiny S-VSON4T package and reduced input power dissipation. The TLP3407SR, features a maximum LED current of just 1 mA at the input, which represents a ...
Microcontroller Displays Voltage Measurements in Graphical and Digital Formats via Single LED Matrix
The algorithm in this microcontroller design this design drives an LED matrix and provides digital-voltage-readout and bar-like dot displays, showing dots for a graphical output if the input value is ...
Input protection for switched mode inverters and converters affects an increasing number of sectors, writes Martin Keenan of Avnet Abacus. Switched mode inverters and converters form the heart of many ...
