i am looking for an DC/DC Converter.
Inputvoltagerange from 24V to 36V
Outputvoltagerange from 4V to 23V
Outputcurrent from zero to 5 A
I need three of these Outputs in my circuit.
It would be great when we could monitor voltage an current from the output.
Many thanks for the supportPhilipp
I see this is your first post so welcome to E2E! For the design parameters you have given, a question about the output voltage: do you want this to be continuously variable? Or will you select a fixed voltage within that range?
I invite you to engage WEBENCH Power Design: www.ti.com/design-tools/overview.html . With the parameters you stated (and I selected a 23VOUT), I see about a dozens designs that could be used; I encourage you to go through the WEBENCH process yourself, determine in these designs what is most important (pcb size, efficiency, etc) and proceed from there.
Let us know what you determine.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Here is a TI Design that uses a DPOT, (TPL0401A-10), to set the output voltage.It would be applicable to any controller or converter that uses classic resistive divider feedback.

In reply to EdWalker:
yes that sounds good with the potentiometer an the LM25145. But at the Linear Side i saw the LTC3884/-1 that comes with all that features exept the voltage range. So is there maybe a chip von TI with the right range and with wide duty cycle range?
Iam not so familiar with the design of DC/DC converter. So witch points do I have to keep in mind so that the controller is stable over the whole area.
