Hello everyone, I am waiting for your help for my university project. I am working on the LED driver. I have no experience in this field, please excuse me if this is an absurd question. The LED specification I will use is 1A, 2.85-3.20 V forward voltage. I will use a li-ion battery for supply voltage. So my input voltage will be 3.7-4.2 V. The switching frequency will be close to 2 MHz. The circuit topology I should use is a Class E converter based resonance SEPIC converter. Can I use controllers produced for SEPIC converters such as LM3410 or LM3421 to control this converter? Or should I use a resonant mode controller? Or should I use a separate circuit with an oscillator and a gate driver instead of a single controller?
