Dear All,
I require some help regarding designing a driver for driving an LED fixture of 72 V DC rating and 300 mA
Is it possible to drive the Mosfet so that upon varying PWM signal from arduino the mosfet Dims and brightens the fixture accordingly.
Any help regarding this will be highly appreciated.
Note:I am using IRF540 MOSFET as of now but the transition is not linear but abruptly switches on after particular voltage given to Gate of MOSFET.
Is there any other MOSFET that can help me in this case.
Thanking You

Hi,
For circuit connections using IR2110 Mosfet driver IC, please refer the following link
https://components101.com/ics/ir2110-mosfet-driver-pinout-datasheet
Can you please share your application along with relevant pinout diagram, so that it would be easy to write a code for it.
Example scenario:
Lets say you have a single MOSFET connected in series with the LED fixture which is used to vary the brightens of the LED.
The brightens can be varied by changing the duty cycle of the PWM signal. For this case study I have considered Time period of the PWM waveform to be 1second.
void setup() {
pinMode(3,Output);
} // Using digital Pin 3 of the Arduino to control the MOSFET. Please refer to the pinout diagram of Atemga if you need to use other digital output pins to control the MOSFET.
void loop() {
difitalWrite(3, HIGH);
delay(600);
digitalWrite(3,LOW);
delay(400);
difitalWrite(3, HIGH);
delay(500);
digitalWrite(3,LOW);
delay(500);
difitalWrite(3, HIGH);

Hi Ranjith
Are tou triggering the mosfet with 5 Vdc?

Hi,
As far as driving the gate of the MOSFET using Arduino is concerned, a current amplifier circuit should be used. Since the output of the Arduino is not sufficient to drive the FET.
Recommended solution is to use IR2110 IC.

Hi,
Adding to the previous response, yes it is possible to dim and brighten the fixture accordingly by varying the PWM signal from the Arduino.
