TN2 Series Flyback Circuit Examples

Posted by: SametDikmen on 03/28/2023


I can't get Flyback circuit samples for TN2 series via PI Expert. When will the version with circuit diagrams of this series come?

I'm not quite sure it's precisely what you  need, but the RDR-623 engineering report details a non-isolated flyback design utilizing the LinkSwitch TN-2.  If you click on the Link TN-2 in the product lineup, it's one of the reference design reports listed following the product description. .

There are no sample circuits for LNK3294 and LNK3296.

OK, so you are specifically looking for example circuits for a couple of the parts with 900V drain rating. What is the intended output power level and end application?

Submitted by SametDikmen on 03/28/2023

Yes, I am looking for a circuit example for 12V approximately 8-10W output power. The field of application will be industrial use.

Two questions, if you please - will the application be isolated or non-isolated?  Also, what is the intended input voltage range?

Submitted by SametDikmen on 03/29/2023

Yes, it will be isolated, Universal input voltage will be provided.

To be able to help you, I will need the actual voltage numbers, minimum and maximum, as well as line frequency.

Submitted by PI-Wrench on 03/30/2023

I don't understand precisely what you mean by "universal" input in an industrial context, since that generally implies a higher maximum input voltage range. The isolated output requirement precludes the use of a Linkswitch TN2. However, the InnoSwitch INN3692C-H606 should be perfectly suitable for your output power range and isolated output requirement. It has a power switch with 900V capability.
