Hello forum,
I'm looking for a circuit that can give a constant average voltage with PWM regardless of the input voltage.
Example: I need 1.5V from a random voltage source. The 1.5V should be the average of a PWM pulse. Eg. the input voltage is 3V, the PWM duty cycle should be 50% to give an average output voltage of 1.5V.
The load for the 1.5V is resistive.
Any suggestions?
Regards,
Futterama
