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…

Hello Ivan,
Summary of requirements:
Vin: 330V - 450VDC
Vout: 12VDC
Pout: 250W
Congratulations on your first time designing a high power and high voltage system! Yes, it is dangerous but TI provides numerous resources and examples for you to get started…
Hi Ijas,
The reason we don't have many reference designs above 1kW with our half-bridge LLC is that this is around the threshold where a full-bridge approach makes more sense. Normally for 2kW, we would recommend our Phase-Shifted Full-Bridge the …
Part Number: PFCLLCSREVM034 Other Parts Discussed in Thread: TIDA-010081 , UCC25640EVM-020 , UCC25660 Hi,
Does PFCLLCSREVM034 support DC input?
For example, 120~375VDC.
If not , why?

Hi Manimuthu,
Have you considered an LLC controller for this power level? This is a resonant topology and can achieve very high conversion efficiencies. We have a new LLC controller the UCC25660 which could easily support this power level. If you want…
Hi Mohammed,
For a 1kW power charger, you can choose between the UCC28064A, UCC28180 , or UCC28070 . For the LLC, our new UCC25660 is well-suited for battery charging applications. This controller introduces Input Power Proportional Control (IPPC). This…
