Part Number: PMP20371 Hi Team,
My customer would like to implement PMP20371 into their design for -48V to 12V application. They need to know if it is possible to add isolation feature to this reference design? If not, is PMP20371 suitable for end application…
Other Parts Discussed in Thread: LM5122 , PMP20371 , LM5158 Hi,
We have required -48V to +5V/1A DC Dc converter, PMP20371(LM5122) is a bigger size. we want a smaller package. please suggest a solution.
Hi Youhao
Sorry, The output voltage is 54V, dose pmp20371 is suitable for the spec?
Input voltage: -34V to -60V range
Output voltage: 54V
Output current: 0.6A
Many thanks
Denny
Hello Sir,
if it needs to be isolated for 100W an Active Clamp Forward Converter is the right choice, UCC2897A.
If it's non isolated a boost controller is needed to build a positive referenced inverting buck boost topology. For this current level synchronous…
Hi Micky,
Thank you for considering LM5122. Are you talking about PMP20371? It could be a good reference. You will need a linear circuit with transistor and zener to regulate the voltage below 65V before supply to the LM5122 input.
Thanks,

Hi Vojta,
Thanks for your interest in LM5122.
You might consider doing the inverting Buck Boost.
Here is a reference design you can look into.

Hello Bell,
If you go to the TI Reference Designs: http://www.ti.com/power-management/reference-designs.html , the closest design we have is an inverting buck-boost PMP20371: http://www.ti.com/tool/PMP20371 .
This could be a good start; you would have…
