This is the top side artwork view of pmp10974.
Is the node 3 of transformer connected to the HV pin(8) of UCC28730?
Why different from the schematic, no problem?
Help me, please. Thank you.

Other Parts Discussed in Thread: PMP10974 , BQ24040 , UCC24630EVM-636 , PMP10478 , PMP11124 , PMP4478 , UCC24636 I need the design details of the main switching transformer used in the reference design PMP10974. The design says only a value (260 uH). Can you…
Hi Mayur,
Here are some simulation resources for the UCC2897A: https://www.ti.com/product/UCC2897A#design-tools-simulation
You may want to also consider a two-switch flyback. Here is a two-switch flyback reference design that is very close to your requirements…
Other Parts Discussed in Thread: PMP10974 Hi,
When I look at the schematic of the reference design PMP10974 I'm wondering about the circutry between the bridge rectifier and the Flyback transformer with the Mosfet Q900.
What I've understand is that…
Hi,
The difference between PMP10974 and PMP11281 is that PMP10974 uses 2-sw Flyback while PMP11281 uses 1-sw Flyback. Therefore, PMP10974 has about 1% higher efficiency than PMP11281. So PMP10974 supposes to have high life time than PMP11281 because…

I assume that this is for universal AC input (90-264 V)?
There are several reference designs on the UCC24630 product page, click on the "tools & software" tab.
