Hi,
I want to learn Topswitch-JX control pin capacitor (47uf series with 6R8) can be replaced with a ceramic type.Any disadvantage during operation or long term reliability?Regards,
Hi,
You can use ceramic capacitor for 47uf, however you need to increase the series resistor value to ~10R. Please read Step 6 – Selection of TOPSwitch-JX External Components in page number 12 in the following application note.
