Led Dimmer Circuit. We are using 555 timers for generating a pwm pulse. The irfz44n is an n channel enhancement type mosfet to it can deliver high output for a simple led dimmer.

If a six digit display is to be current limited at least 42 series resistors are needed. We are using 555 timers for generating a pwm pulse. Then the pwm pulses drive an n channel power mosfet.
That is pretty much it and you can use the circuit for led dimming.
If a six digit display is to be current limited at least 42 series resistors are needed. The collector led load current is essentially the same as the emitter current. In order to get led lamps to dim you need a proper pairing between the lamp and the controls. A basic led driver circuit cannot be dimmed from a triac based dimmer without some additional components being added to enable stable dimmer operation and then to adjust the output current based on the dimmer phase angle.
