Part Number: LM5119 Other Parts Discussed in Thread: PMP , TINA-TI Hi team,
I have downloaded simulation model for LM5119 and try to run simulation in Tina ti. But i am unable to run it. It shows error in simulation at some nodes which are not visible…
Part Number: PMP10979 Other Parts Discussed in Thread: LM5119 , Per reference design PMP10979 using LM5119 in parallel, is there a recommended add-on circuit perhaps to the FB2 node that allows some limited output voltage adjustment from 5V to 12V at maximum…
Part Number: UCC39002 Other Parts Discussed in Thread: LM5119 , PMP10979 , PMP10979 is described four phase LM5119 solution.
Part Number: LM5143-Q1 Other Parts Discussed in Thread: PMP10979 , , LM5143
Hello Support team,
Can LM5143-Q1 support 4 phase operation like PMP10979 by using two LM5143-Q1? 4 phase would requires, stop both error amp on slave LM5143 and support external…
In my opinion, both MC34063A and UC3525 are not suitable for this high output current application, because they don't feature the synchronous function, which will cause a large power loss.
The reference design PMP10979 is closest to your requirement…
Please refer to reference design PMP10979.
www.ti.com/.../PMP10979PMP10979 uses LM5119 which is pin to pin compatible with LM25119.
If you have more question about 4phase operation, please let me know.
Other Parts Discussed in Thread: PMP10979 Hi,
does anyone can help to recommend solution me?
The input voltage : 12V,
The output voltage : 8.1V
The output current: 72A
The priority of customer selection :
2. easy to design
It is doable. The inductor size would be large.
Another option is to use 2*LM5119 (4phase) for 80A design. 4phase design will have better thermal, load transidnet, ripple performance.
Attached is the schematic and test result of 4phase reference…
We have 4phase interleaved reference design with 2xLM5119.
LM5119 and LM25119 are familar device with the same pinout. The reference design can be refered for 4phase LM25119 design.
Attached is the sch and test report.
