Flybuck LM5160

Other Parts Discussed in Thread: LM5160

Webench doesn't do multiple output simulations sadly so I'm hoping someone can confirm whether or not this is a good idea.

+/-5V @600mA on secondary windings using versa-pac inductor. The Isat is 6x in a flybuck configuration (according to note 4 on their datasheet) so I'm hoping I can use it in a 1:1 configuration.

Thanks.

Hello,

What is the Vin min? Ideally needs to be 10V and above. You can certainly use a Versa pac, make sure the Isat rating is greater than the Current limit max of the LM5160 [2.875A]. Ideal selection is 22uH, but you can relax the peak to peak ripple current in the inductor using a 12uH. Hope this helps?

I plan to use two windings in series to get more inductance so I expect everything should be alright. Thanks!
