Hi all! I have a question regarding obtaining an average DC voltage.
Example, I have a square wave of 10Vdc peak, duty cycle 70%.
Is there any circuit or IC that is able to convert this square wave into a constant flat DC voltage to 7V?
As the duty cycle varies from 10%-90%, I need some circuit or IC that can dynamically vary between 1V to 9V, depending on the input duty cycle.
I was thinking of using a LPF, but seems like the capacitor would still charge upto the maximum 10Vdc after sometime.
Thanks all!
