Part Number: UCC29002

Hello

We are going to configure the system as follows.

I would like to apply load share using UCC29002 to this system.

Could you provide a reference data when the output is 110V for the isolation type?

Best regards.

Hello Louis Han15

The reference designs, application data, calculators, data sheet and all available information required to use the UCC29002 is available on this webpage.

Hi John

I have checked the data on the webpage, but the reference to the high voltage load share is not confirmed.

What should I do when designing a high voltage load share?

Best regards.

Hi Louis,

Figure 5 of the data sheet shows an application for a high voltage output.
The npn transistor limits the voltage on ADJ to VDD-0.7v
For your 110V application I suggest you use a separate 12V bias supply since it is not really feasible to divide down the 110V with RBIAS1 and RBIAS2 resistors.
You will need a 150V or greater NPN transistor.

John
