Part Number: UCC256403 Tool/software: Dear Experts
I have tried with the values in the range that disable the burst mode. But burst mode is not disable.
Another thing I observed that after removing upper resistor of BW. I observed that burst mode is…
Part Number: UCC256403 Tool/software: What are the ways to disable the burst mode at the defined output current?
I have tried with selecting option as per the datasheet but I have observed at burst mode is not Disable and output voltage is controlled…

Hi TI,
I would like to contact you because I'm just starting to manipulate my first LLC, and I'm having a few problems with UCC256403 in startup.
The controller starts…
Part Number: UCC256403 Tool/software: Hello, What is the risk of starting the PFC 400V voltage before the LLC 15V control circuitry? Since the LLC drivers are not active, is it possible that this could cause the converter to break? This question is a…
Part Number: UCC256403 Tool/software: Hi
I am Using PC817 as my feed back optocoupler whose input connected to CC CV loop outputs with OR Gates
By seeing the Below image As one of the Diode conducts the Base current would be approximately ( 0.94mA)

Part Number: UCC256403 Tool/software: 1.Abnormal phenomena
In our half-bridge LLC design，when UCC256403A works in burst mode at very light load （typically 0.2A/48V），it sometimes goes in an abnormal control .Show as the picture1，at the end of some burst…
Part Number: UCC256403 Dear Expert,
We are working on charger 650W Design using UCC256403.
We have CC CV control implemented using OPAMP.
Voltage and current ripple are minimum during CV operation while we are getting more current ripple in CC mode.
…
Part Number: UCC256403 Tool/software: Hi,
We are working on 1200W EV charger (58V, 20A).
Also we are using UCC25640x Design Calculator for calculating & tuning Ln, Qe, Lr & Cr.
In this tool some of the cells are password protected.
Could you…
