LM3880: How to calculate the delay time with external RC circuit

Webber Chang
Prodigy 130 points
Part Number: LM3880

Tool/software:

Hello,

I place an RC circuit on the EN pin using a 51K ohm in series with a 4.7uF capacitor, could you please guide me on how to calculate the delay time of flags?

If you could share a calculate tool, that will be greatly appreciated

Sincerely

webber

    HI

    Why do you need 51K resistor? if you want to use capacitor to delay the EN, you shall just connect the capacitor on the EN and use the formula inside the data sheet

    Regards
