Part Number: UCC25661 Hello,
I am replacing the obsoleted UCC25660-2 with a UCC25661-2 part and are having expected random bursting at light load (~10%). Initially another engineer was working on the issue, and it has been reassigned to me.
I…

Hi Sir,
When will TI release the simulation model of UCC25660 and UCC25661?
Thanks.
Part Number: UCC25661 Hello TI team,
I’m using the UCC25661 resonant controller in a custom LLC converter design and would appreciate a design review and guidance on startup behavior. Despite switching activity on the half-bridge, I’m seeing no output…
Part Number: UCC25661 Hi,
I have few questions regarding this IC as i decided to use this IC in my LLC resonant converter.
1.) Can i get 7V gate pulses using this IC or any similar LLC controller IC.
2.) Can I power the IC externally? (Not using…

Part Number: UCC25661 Tool/software: Hello, could you share what the differences are between the UC25661x ordable part numbers?
In the calculation tool, you can pick different model options and there is a table showing some differences. But, for example…
Part Number: UCC25661 DC-DC converter
Vin = 43-160 VDC
Vo = 15 V
Po =150 W, Isolation required, High frequency
For these parameters on TI webench tool, LLC resonant converter is recommanded.
My question is is it can really cover this much…
Part Number: UCC25661 Tool/software: Dear team,
there seems to be a mismatch in the datasheet regarding the RFB specification.
1) Figure 6-7. shows a plot with approx 103kOhm vs. temperature.
2) Under section 6.5 Electrical characteristics we specify…
