Hello

I am using LM73606 part in my design. I connected the Pgood with pull up resistor to 5V by external LDO.

I see the 1.05 output but the Pgood is 0V. what can be the problem?

    Hello

    Be sure that your output voltage is correct and is not oscillating.

    Try to reduce the value of your feedback divider resistors.

    As an experiment, try to short out the top feedback resistor.

    Be sure that nothing is shorting the PG pin to ground and that your pull-up supply is correct.

    Thanks
