Hi ,
i was trying to simulate the UCC21551 gate driver section with UCC25800 as power supply to it, Ucc21551 part was working but we i tried integration with UCC25800…
Part Number: UCC25800-Q1 Other Parts Discussed in Thread: UCC25800 Tool/software: On page no.31 of the datasheet of UCC25800-Q1, the value of parasitic capacitance at pin SW is mentioned as 170pF. Is this the parasitic output capacitance value across…
Part Number: UCC25800-Q1 Tool/software: HI,
I need one clarification on Fault code monitoring.
From datasheet, DIS/FLT is active low pin and once the fault is detected it will give 10us pulses.
here my questions is, do we get the 10us pulses continuously…
Part Number: UCC25800-Q1 Tool/software:
On page no. 30 of the datasheet, the turns ratio calculation shown for the design process of the LLC converter's transformer, the formula includes the voltage drop of both the diodes of the output rectifier instead…
Part Number: UCC25800-Q1 Other Parts Discussed in Thread: PMP40980 Tool/software: Hello!
I'm using UCC25800-Q1 in an application similar to this: ( Bias Supply Design for Isolated Gate Driver Using UCC25800-Q1 (Rev. A) (ti.com) - Page 17)
ISSUE:
The…
Part Number: UCC25800-Q1 Other Parts Discussed in Thread: UCC25800 Tool/software: Dear TI team
I would like to confirm something about the UCC25800-Q1.
I am considering adding an external circuit to protect this device from overheating.
The DIS/FLT…
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…
