Part Number: UCC256404 Tool/software:
OPTO Current Transfer Ratio
CTR
0.4
If the CTR specification of a photocoupler is 50-600%, should I enter a number between 0.05 and 0.6 in this field?
Part Number: UCC256404 Tool/software: Hello,
My customer wants to implement an LLC converter. Could you please send em so I share with customer Spice model of the chip or one that is compatible with?
Thanks,

Part Number: UCC256404 Tool/software: Hi This is Jongyoon,
I am currently designing a LLC converter with UCC256404
I have a question regarding the value of VFB Clamp Voltage.
In the datasheet of UCC256404, it says that VFB voltage is clamped when it…
Part Number: UCC256404 Hi TI team
I have query on UCC256404 LLC controller
1. If i use capacitor split method for Half bridge LLC and the split capacitors due to its tolerances top and bottom half voltage will have different values(lets say 210V on top…
Part Number: UCC256404 Hi TI team,
I have a query on LLC controller UCC256404 .When burst mode is disabled, FBreplica needs to be higher than BMTL at steady state. Otherwise, LLC output voltage will lose regulation as it continues deliver more energy…
Part Number: UCC256404 How to select the resistor divider on the LL/SS (pin 9) if we are using in burst disable mode (option 7). Since the LL/SS pin sets the threshold to burst mode?

Part Number: UCC256404 Hi.
This is Jongyoon and I'm designing a LLC resonant converter by using UCC256404.
As I noticed, The design file (Excel) that TI offers has a protection on it and needs a password to unlock it.
Is there any chance that you…
Hi Manikanta,
You were right, I adjusted the VCR caps and it's working perfectly now. I really appreciate you and Mike's patience. Thanks again for your help!

Part Number: UCC256404 Hi Team,
Customer chose UCC256404A as the BW OVP Mode is latch mode. That means the RVCC will change to 0 and will keep to 0 when the fault is asserted, right?
After the fault assert, how UCC256404A can go back to work normally?
