Part Number: PMP9253 Other Parts Discussed in Thread: LM5022 , LM51551 Tool/software: Hi,
I am looking for high efficiency low-cost isolated dc -dc converter design for the below specification, kindly refer the reliable and proven reference design from…
Part Number: PMP9253 Other Parts Discussed in Thread: PMP11012 Hello,
We are working on one of our C2000 EVM which requires isolated power supply with similar or improved specification as reference design PMP9253 (Vin(typ) = 48VDC (max 60V), Vout…
Part Number: PMP9253 Other Parts Discussed in Thread: PMP10506 , PMP40274 Hi TI
Can we change the power transformer to PA5130.005NL to support 5V/6A output?
Any other BOM change needed?
Fortinet, Colbert Hsu
Part Number: PMP9253 Other Parts Discussed in Thread: LM5022 I would like to use PMP9253 (similarily design) to provide 10-60V input and 3A@+15 output isolated, change the transformer to 1:3. Will the design work base on PMP9253.
Other Parts Discussed in Thread: TLV431 Dear all,
is is possible to change the output voltage from 5 V to 5,5V-7.5V on this board PMP9253 ?
If yes, what components do i have to change and can the transformer (PA3855.005NLT) stay the same?
Best…
Hi Hirotaka,
You should be able to use same topology for your requirement.
You can consider LM5022 with CSD19534Q5A, which is a very low RDSon and QG MOSFET.
You need to recalculate transformer, current sense and feedback network components.

Part Number: LM5022 Other Parts Discussed in Thread: PMP9253 Hi Sir
I used the LM5022 be the flyback converter.
Attached is my circuit.
SCHEMATIC1 _ 05. FLYBACK.pdf
When I saw the TI document, the D4 and D5 are DNP.
Here is the circuit which…
Part Number: LM5022 Other Parts Discussed in Thread: PMP9253 Hi,
we use LM5022 as flyback, the input is 7.5V to 57V, output is 5V/1A, reference to PMP9253.1,
The transformer is the same with reference design.
the question is, when input is 9V and…
Hi Bernard and Bhavdipsinh,
Thanks a lot for prompt help, since there are multi outputs, we may propose the below solution,
We have PMP10532 based on LM5160 cover the following
+12V 0.25A
±5V, 0.3A (isolated)
And PMP9253 based on LM5022 cover…
Hi Kishi-san,
looks like a good start. There is a very similar design PMP9415 you may like to look at.
With regulated feedback you may like to look into PMP9253 based on LM5022.
Other then this there are some application notes you or your customer…
