Simple LED Driver

This projects shows how to power LED’s with a simple Mosfet Circuit. The circuit will use the following components.

  • IRFZ44N Mosfet
  • 10k Potentiometer
  • 10k ohm Resistor
  • 200 ohm resistor
  • 1 Watt LED
SCHEMATIC SUMMARY

The circuit will work with a wide range of voltage input. The current can be adjusted with the potentiometer if the input voltage changes. With a 1Watt LED the mosfet sustained a low operating temperature. The 200 ohm Resistor may need to be increased if the input voltage is higher than 12 Volts. Overall the Circuit works really well.
