Hi, I've got a 0-5V 5MHz (high frequency for a smoother analogue signal) PWM signal that can provide a maximum of 30mA, that goes into a low pass filter so I can convert it into an analogue signal.
I want to be able to draw up to 2A (without overheating or setting it on fire of course). I could just put a transistor, but correct me if I'm wrong, but the voltage drop across a transistor varies depending on the current drawn, and I need to know the exact voltage vs the PWM cycle.
Is there any circuits or chips that'll let me do this? Thank you
