LM25183: Isolated power supply solution

Tool/software:

Hi,

We are considering a simple isolated power supply configuration for a new application.

①Vin +12V, Vout +5V, Iout 500mA
②Vin +12V, Vout +24V, Iout 300mA

As far as I know, isolated modules with built-in transformers (such as UCC14130-Q1) that can be realized with a simple configuration are often optimized for a 1:1 transformer ratio, so I think they cannot be used under conditions like ①. Therefore, the optimal solution is probably to use a flyback.

I would like you to suggest a recommended configuration for the step-down and step-up isolated power supply solutions of ① and ②.

Thanks,

Conor
