Part Number: TPS54540B-Q1
Other Parts Discussed in Thread: TPS54540B

Hello,

Is there a possibility to use, to customize and to simulate the TPS54540B for a negative output voltage in Webench Power Designer tools ?

This kind of topology :

It seems Webench does not propose this topology.

I thank you in advance for your answer.

Best regards,

Hello Dominque,

The WEBENCH tool does not have this option for simulating.

However we do have a design guide app note that you can refer to for steps to converter a buck device to inverting buck (https://www.ti.com/lit/an/snva856b/snva856b.pdf).

I would suggest you follow the guide in this instance.

Regards,

Jimmy
