PWM INPUT CONSTANT CURRENT POWER LED DRIVER Schematic Circuit Diagram

Power led driver circuit LM393 The PWM input according to the other led drivers on the op amp works well without PWM, but it is possible to input PWM from microcontroller or other sources. Three different power options are available. 1W power LED 350mA, 3W power LED 700mA, 5W power LED 1A R2, R11 resistance values ​​are determined according to the desired power.

High energy efficiency switch mode converter. 5V-24V supply voltage range. . Cycle-by-cycle, true constant current circuit 1A adjustable output current 18W maximum output power. (For 3w led modules working with 24v ) current control with potentiometer (with about 9% spacings)

Output short circuit protection PWM input – can be controlled via external microprocessor including Arduino. Compact design – 1 x 1.5 x 0.5 inch (excluding pot shaft)
