Tool/software:

Dear Team,

I need to generate an power from a 24V source to a +15/-15V output voltage. But the output currant is quite high a least 3A.
Can a use two TPS62901 one for the +15 and one inverted to -15V ?

Thank you

Hi Sir,

Sorry, TPS62901 cannot support such condition.

We have TPS62933 can support +15V，

For -15V, you may need ask wide vin buck produce line for advice.

Thanks

Colin

Hi,

thank you for your answer.
Do you think the LM5116 is fine to generate -15V @6A ?

Yes, controller can be used in this application.

But i am more recommended to use LM5146 as it is newer device.

Thanks,

Colin
