DC-DC Converter for Driving High-Intensity Light-Emitting Diodes with the SEPIC Circuit

This whitepaper explores the challenges of powering new 350 mA LEDs, emphasizing the need for a constant current source due to varying forward voltages and temperatures. It introduces the single-ended primary inductor converter (SEPIC) as a solution, capable of handling input voltages above and below the LED voltage, with smooth input current and a single switching transistor.
