Part Number: TPS23754 Other Parts Discussed in Thread: PMP6812 , , PMP6672 To whom may it concern.
Hi, I'm HS.
I've got TPS23754EVM - 383. Now I want to use it with flyback.
I happened to find the reference called PMP6812 - Class 4, Cost-optimized…
Hello Can Liu.
Have you searched our portfolio of online TI Designs? I think the following design would prove helpful in this case --> http://www.ti.com/tool/PMP6672
It's features are:
* High efficiency(90%), converter only efficieny is 92…
Other Parts Discussed in Thread: PMP6672 What efficiency can be expected using the schematic at:
a) First page of http://www.ti.com/lit/ds/symlink/tps23754.pdf
b) Figure 27 in the same datasheet.
Other Parts Discussed in Thread: TPS23756 , TPS23754EVM-420 , PMP6672 , LM431 , TL431 , TLV431 , TPS23754 , PMP7452 I'm currently trouble shooting a design based around the TPS23756. It is based on a mix of the various flyback reference design for this series…
Hello,
The transformer is one of the most important parts of a design that determines the system's performance. 8.5V is a non-standard output voltage for PoE, so you probably won't find many reference designs with it. I'll do my best to layout some options…
Hello again na na78. Nice to hear from you.
A 5V / 6A design would actually equate to a 30W design - which is beyond the IEEE802.3at complaint power limit of 25W. Are you interested in achieving IEEE802.3bt readiness and designing an official Class 5…
