Part Number: UCC28782EVM-030 Hello:
Wondering if it is possible to inject the small signal while setting up an SMPS for loop gain-phase measurement with a nonisolated opamp for its broadband properties but of course, the limiting factor is the output…

Pl see attached ppt copied from the EVAL kit document.
The table shows how Rdm & Rtz change with load.
How does one interpret the Table?
It is clear that a…
Part Number: UCC28782EVM-030 Hello Mike:
What would be your explanation for the theory of allowing to use of the same nodes to measure loop response as Vout/Va as the nodes where the signal is injected with floating nodes from the transformer?
Therein…
Part Number: UCC28782EVM-030 Hi team,
I know we can use type-c PD to achieve different Vout (5V/9V/15V/20V), but how to judge the OVP can be latched at different Vout?
BR,
Jimmy

We have some UCC28782 based modules: assembled with values close to the UCC28782EVM-030 EVAL KIT. Right now, input is rectified AC with sufficient input filter and…
Part Number: UCC28782EVM-030 Hello
We made a xmfr 40:8:8
Which should have reduced Bac 60%, thus hopefully, DC bias value.
But it did nothing to reduce core temp. We ran 100W ...stopped when inside the core temp went up to 130 deg C.
Temp rise is not…

In the UCC28782EVM document, they mention PM110.
It cannot be found anywhere.
We are not yet ready to fork out $1000 bucks for testing with anything other…

We have briefly discussed how UCC28782 behaves under WT6636 control if it wants to have 5V output. Even 9v will be problematic we think......maybe 12v, 15v ok. Our experience…
