Hi Cyril,
I had a look on the application and would have some additional ideas, if you are still in the design phase.
Regarding the component LM3478, we have newer controller parts within our portfolio that run with modern process and have better pricing…
Part Number: LM5155 Other Parts Discussed in Thread: LM3488 , PMP40488 , Hi,
I am currently designing a dual high voltage power supply based on PMP40488 reference design, from a 12V source supply (we were previously using the same topology with the LM3488…
Hi Gerald,
PMP40488 is the closest design that I could find. It generates adjustable outputs from 0 to +/-60V using the LM5155.

Hello,
The customer can use the LM5157 in flyback configuration, there is a flyback EVM with 4 outputs available on the product folder ( https://www.ti.com/tool/LM5157EVM-FLY ), the schematic is at page 13 of the user's guide ( https://www.ti.com/lit…
Hello TecnoLAB,
Sorry for the late response.
Please have a look at this reference design: https://www.ti.com/tool/PMP40488
This is a SEPIC converter, but you could try to do a similar design with removing the coupling capacitor and using a coupled inductor…
Hi Lee,
I suggest taking a look at the following reference design. This implements the LM5155 (similar to the LM5156) as an uncoupled SEPIC controller with a positive and a negative output voltage. This design can be easily changed to meet the application…
Hi A.S.
I have a few ideas for the power supply. I think a good solution would be to use the LM5155 in a dual SEPIC configuration similar to
https://www.ti.com/tool/PMP40488
However the power level of that particular design is not close to what you need…
Hello,
Sepic can be used in your application.
I recommend looking at this thread for more information on designing a SEPIC converter.
