Controlling the brightness of LEDs requires a driver that provides a constant, regulated current. To achieve this goal, the driver topology must be able to generate a large enough output voltage to ...
While searching for some SEPIC converters (https://en.wikipedia.org/wiki/Single-ended_primary-inductor_converter), I came across a popular power supply module that is ...
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 ...
Worcester, MA – Allegro MicroSystems, LLC introduces two new devices to complement their existing portfolio of LED Driver ICs for LCD backlighting applications. Allegro’s A8518 and A8519 devices ...
Due to their light output and long life, high-brightness LEDs are well-suited for use in flashlights. Typically, the LEDs are driven with a constant current. So when the battery voltage drops, the ...
