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?
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…
Part Number: UCC256303 Other Parts Discussed in Thread: UCC25600 Hello,
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…
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…
Part Number: UCC256303 Referring to datasheet page 16, the block diagram indicates the LL/SS pin should only source a small current during soft start (ChargeSS, which I assume corresponds to the I_SSUp specification---please confirm?), or sink a modest…
