Refer the attached schematics, I have a system as below, controller runs at 200 kHz. I have a requirement of interruption at the controller voltage for 50 μs, still during that I need to have the PWM running. I have one option to have hold circuit for the controller to stabilize the voltage, to avoid the big Cap to be used. I thought of using PLL in between. But the PLLs duplicates the frequency! What could be considered ? any suggestions.
