Other Parts Discussed in Thread: LM5020

Hi there,

I need to design an isolated DC/DC power supply, Vin 10~14V; Vo: 5V, Io: 2A, 40C temperature, there are so many options, any suggestion on IC for circuits with reasonable cost/size/efficiency trade-off?

Thank you very much.

For your input, and output requirements, I would use a Flyback topology I recommend looking at the LM5020. You can find a reference design online that is close to what you need, I have attached the link. http://www.ti.com/tool/lm5020eval
