Part Number: UCC256303 Tool/software: Hello expert,
My customer is using external Lm choke. They would like to know how to design core size / turns number to make core have enough saturation performance and Lm inductance? Do we have application note…
Part Number: UCC256303 We are using LLC half bridge topology for designing a DC DC converter from 400V to 220V dc using UCC256303.
The power level is 2 kW for my purpose.
1) Whether it is suitable with halfbridge topology? Since Iam not seen any reference…
Part Number: UCC256303 Hi Team,
My customer is asking regarding the VCR Pin of our UCC256303.
According to TI SIMPLIS simulation tool, we think that VCR is an AC signal.
Should the rating be -7V~+7V?
BR,
Alfred
Part Number: UCC256303 Other Parts Discussed in Thread: UCC256403 Dear TI,
My team is now using UCC256303 as HB LLC controller.
I've notice that there's a update version which is UCC256403, one of the major different between them is minimum detectable…

Hi! My name is Jae Ho Lee working in LS Electric.
In current, I am developing 3kW LLC converter, which is used in UCC256303.
I used the anaother gate driver for gate voltage level shif…
Part Number: UCC256303 Other Parts Discussed in Thread: UCC256403 Good day,
I'm currently working on custom design of LLC DCDC converter with the following specifications: Vout = 13V, Pout = 260W, Vin (min) = 280V, Vin (max) = 440V, frequency (LLC) …
Part Number: UCC256303 Hi,
Can this IC be used for low power application based on LLC design.
My requirement is - Vin= 6-40V, Vout = 24V, power = 1-5 W.
Any other similar IC available with secondary side regulation for LLC convertor for above operation…

In the following URL, we were taught about the LLC compensator design.
UCC256303: How to set Burst Mode Programming? - Power management forum - Power management - TI E2E support…
A better optimzed resonant tank helped. But I was also using a too low input voltage. When I increased from 320V to 390V it improved. I was switching at below resonance.
Hello Manikanta,
I adjusted the FB circuit so that the FB voltage is at least 4V, but I have not been able to release burst mode yet.
Therefore, we obtained SIMPLIS and analyzed the circuit by simulation.
The SIMPLIS model of UCC256303 was downloaded…
