Part Number: UCC25800-Q1 Other Parts Discussed in Thread: UCC25800 Tool/software: Hello,
I am using UCC25800-Q1 as a part of my design for LLC resonant converter. I am using 18K and 15K with tolerance 2.5%. The OCP1 threshold setting depends on this…
Part Number: UCC25800-Q1 Tool/software: Dear team,
I see the operation wave form with fsw = f_res and fsw < f_res on Figure 9-6 on the datasheet. Does this IC work properly in case fsw>f_res? (where f_res = resonant frequency of LLC circuit.)

Part Number: UCC25800-Q1 Tool/software: Hi,
I am currently working on designing an LLC resonant converter based on the Texas Instruments document SLUAAB9A. However, I am facing an issue where the simulated current on the secondary side of the transformer…
Part Number: UCC25800-Q1 Tool/software: Hi~ team:
When our customer was testing the DEMO, it was found that when VIN_12_MUX is different, the +15V_HOT_HS_I is not a fixed value, and at low voltage (9V), the output (VDD_HS) is less than the expected value…
Part Number: UCC25800-Q1 Tool/software: Hi, I like to choose OCP1_6 OCP setting for the UCC25800-Q1. This with Ra=Rb (as of Maximum dead time selection). Resistors should be out of E24. So I have chosen Ra=Rb=5.1k. But with this I'm right at the edge…
Part Number: UCC25800-Q1 Hello
We are currently designing a dual voltage supply, and we have the problem that our IC goes into error mode if more than 220mA are drawn or after 20 min goes also into error with 190mA. We measured our deltaU which is stated…

Hello,
I am trying to build the UCC25800A-Q1 IC using basic blocks and simulate its behavior in SIMetrix, Can you please provide details of parasitic elements of MOSFET. It…

Hi
I wanted to go with a multiple secondaries approach, where my previous design is distributed one, I wanted to know that from the highlighted text that
1) Is there any hardware change…
Part Number: UCC25800-Q1 Dears:
Input voltage is 15V, C102 voltage set value is 22V, when add 60mA load , C102 voltage will drop to 20.9V, I have checked schematic, seems it's OK. I wonder if it can be improved by adjust transformer.
Could you please…
Part Number: UCC25800-Q1 Hi Expert!
Can this device use multi-winding transformer to supply several isolated output? I am not sure should I use the primary resonant method or secondary resonant?
