Part Number: PMP7899 Hi,
I would like to reference PMP7899 and modify to Vin 12V to vout 54V 60W application,
But webench only for non-isolated design.
Would you please tell me how to modify to this application?
thanks!
Jeff
Other Parts Discussed in Thread: PMP7899 Good morning,
I have realized the circuit of PMP7899 project. In order to do this, I required the transformer at Coilcraft.
So I mounted the circuit, but it doesn't work correctly: AT NO LOAD If I supply the…
Hey Moritz,
Thanks, these are great resources.
I just have a question about the zener placement. Your original response has the zener placed inline with Ropto, however in the "Power Stage Designer - Loop Calculator" it has the zener clamping the voltage…
Hi Mike,
Please see the design below it is a pretty good fit for your requirements. It does not exactly meet them, but will give you a good idea of what the design should look like.
Thanks,

Hi Jeff,
Thanks for your interest in LM5021.
We do not have a reference design with LM5021 used in a boost (12V --> 54V) topology (max 60W).
The design I found that most closely matches your description is https://www.ti.com/tool/PMP7899 .
If…
Hi,
There are two reference designs that provide isolation and boost the input voltage from 12V. These are the PMP5518 and the PMP7899, both are in power labs. The output voltage is lower than the application but the transfomer turns ratio can be changed…
Sid,
If you refer to the TI Powerlab reference design section
http://www.ti.com/lsds/ti/analog/powermanagement/reference_design.page
and input the design parameters, you will get a list of posssible designs.For example the LM5022 is used on the…
