HI Ryan,
The UCC25640 is a pin to pin drop in. You will have to modify the bill of materials as explained here .
Note, while not pin-to-pin we have a newer controller that is even easier to design with and can resonate at much higher frequencies. The…
Hi Anuj,
You can use our newest LLC controller if the hard switching is a biggest concern for you: UCC25660 data sheet, product information and support | TI.com . This has a feature that can avoid hard switching at startup.

Hello Nilesh,
You will first need a PFC controller after rectifying the universal AC input. If your total power is >75W, then PFC is required per EU standards . What is your total output power? This will determine what PFC controller is optimal. Please…
Hi Conor,
What power level are you trying to support? The UCC28180 is a pin to pin drop-in replacement option. The interleaved UCC28070 is typically used for higher power applications. If you are looking for higher operating frequency for higher power…
Hi Ahmad,
Unfortunately, we do not have a Pspice model for this or our newer UCC25660 controller. The reason is that a Pspice model would be very slow and difficult to run. Simplis is a much faster simulator that is less prone to convergence issues. …
Hi Ahmad,
For question #1. The absolute maximum rating of the VCC pin on the UCC256402 is 30V with the recommended operating voltage being from 13 to 26V. If you do not need the HV startup, the UCC256403 could be an option.
For question #2, PMP1012…
Hello Rizwan,
Due to your wide output voltage range, Full-Bridge LLC is not recommended for your design. A PSFB is more suited for a wide voltage output range at high power.
A FB-LLC revolves around a resonant tank, which is designed for a specific frequency…
