Manikanta Pallantla said: Coming to the standby operation, UCC25660 does have the burst mode operation. So, I would still recommend using this new controller at such a high switching frequency.
I cannot use burst-mode due to EMI.

Part Number: UCC256403 Tool/software: Hi Sir :
I have the following questions regarding this chip :
Question 1: Is there any way to determine the design margin of OCP2/OCP3 for this chip through testing or theoretical calculations? Question 2: Will the…
Part Number: UCC256403 Other Parts Discussed in Thread: TLV431
Tool/software:
The VFBreplica voltage and the IFB current is a bit unclear in the datasheet for UCC256403. Since the datasheet is lacking in information, I've scanned the TI forum for answers…
Part Number: UCC256403
Tool/software:
In the example simulation for UCC25640x (given by slusd90 - june2019) ideal switches are used instead of HIGH side and LOW side MOSFETs. In this simulation model there's no problem getting clean waveforms with high…

I have the following question about the parts used in the peripheral circuit of UCC256403.
In the example…
Hemanth Sreeperumbudur said: I entered RBW value to be 0kohm and 1uA as initial current in the default circuit downloaded from web. I don't see burst mode until the load is applied, when the load is applied, continuous switching is observed. However, once…
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…
Part Number: UCC256403 Tool/software: Hi TI Experts,
I have designed 1.5KW LLC DC/DC converter using UCC246403 after my PFC stage. I have to gain 3% more efficiency to meet my requirement.
My HF transformer details are below.
Core= PQ4040
Np/2=12Turns…
