Hi, I am using a 2kHZ PWM 0-5V signal 0-100% duty cycle to control a N-Channel MOSFET ( IRL2910 ) . The idea is to control up to 3A of current through the drain/source. The principle works fine but the current fluctuates by around 150mA. Is there a better design or would you know of a better MOSFET …

N-Channel MOSFET - Current driver

What's the load? Inductive?

What's the PWM TOP value?
How do you control the PWM duty cycle?
