Part Number: PMP21683 Hi TI experts ,
am trying to copy PMP21683 , already get the LLC X'former spec which is not integrated with additional leakage;
can you advise me the inductance of RLTI-1304 of that external Lr ? thanks
Norman
Part Number: PMP21683 Other Parts Discussed in Thread: TL431 , UCC256302 Hi , I modified PMP21683 48V 500W design to 24V version ; LLC Xformer turns ration from original 29:3:7:7:2 to 32:3:4:4:2 ,
Primary inductance stay 230uH without change , additional…
Part Number: PMP21683 Hi ,
do you know the p/n of the Core ( EFDxx or EExx or ERxxx....) and bobbin ( 20 pins with pin pitch and space ) for that 250uH LLC Transformer ( T100) ,
since I had a PCB built by this reference design gerber , assembly need to…

Hello Sravan,
We have a topology selection for isolated DC/DC controllers here: https://www.ti.com/power-management/acdc-isolated-dcdc-switching-regulators/overview.html . Looking at this chart, an LLC or PSFB could be a good option for you.

Hi Mitchell,
One concern I would have is with the tolerance of the turn-on threshold, you may have cases where one UCC24624 decides to turn on but the other does not. The two gate drives would fight each other with one trying to turn on and the other…
Hi Catur,
For 48V/500W, take a look at PMP21683 + PMP21366. Together, they would form a PFC + LLC to meet your requirement.
For 5V/300W, take a look at PMP21366.
Best Regards,
Ben Lough
Hi Vakhtang,
Sorry for the delay here. I'm not too familiar with all the TI Designs since these are done by many engineers within TI across different end equipment. I imagine these fulfill specific input requirements for a broad range of end equipments…
