Hi Bernd
Thank you, that's very detailed. By the way, I see a BAT54S-7-F in PMP20551 as the figure below, what's the function of these two diodes? Is it necessary?
Part Number: LM5022 Other Parts Discussed in Thread: LMV431 Hello,
in the Design ( http://w*ww.ti.com/lit/df/tidrqf9/tidrqf9.pdf there is T1 (750316708) from Würth.
The truns ratio pri1 to sec is 3:1.
Vin: 12 to 60V.
The secondary winding is defined…
Part Number: LM5022 Other Parts Discussed in Thread: PMP20551 Hi,
I saw the LM5022's demoboard PMP20551.
the transformer turns ratio is 3:1, it means duty about 80%
The general recognition is that the duty cycle of flyback is less than 50%. What…
Part Number: LM5022 Other Parts Discussed in Thread: PMP20551 hi,
I saw the Reference Design PMP20551.
I want to know the Transformer T1's detail Specification for my design.
Could you provide this for me?
thanks.
Part Number: LM5022 Other Parts Discussed in Thread: PMP20551 , Hi,
I'm using the PMP20551 ( http://www.ti.com/tool/PMP20551 ) reference design to design a PoE flyback transformer circuit which outputs 24VDC/3A.
I've found the "PoE transformer 750343576…
Part Number: LM5022 Other Parts Discussed in Thread: PMP20551 TI Designed PMP20551 : T1 Transformer parameter is ? I am in Wurth Elektronik web, DOWMLOAD the datasheet,There are no specific parameters; pls hlep!
Part Number: LM5022 Other Parts Discussed in Thread: PMP20551 Hi Team,
Good day. I am posting this inquiry on behalf of our customer.
My concern is that you have design support you Wurth Ekerronik company transformer and I need substitution because…
Hi Jan,
Unfortunately, I do not have a recommended solution for a transformer. In order to utilize that specific transformer, you would need to connect multiple winding together to generate the appropriate turns ratio.
However, what I can do for you…
Hi Robert,
LM2587 minimum current limit value is 5A, which is not big enough for this application.
You can take a look at the reference design: http://www.ti.com/tool/PMP20551
Hi A,.
I recommend using the TPS23756 for the 12V/2.5A solution since this is a Type 2 application. I recommend using the same power stage as PMP20551 except using the TPS23756 PWM Controller. For the Type 3 24V/2A, I recommend the TPS2373-3. Unfortunately…
