Hi Sir

1. May I know TPS63710 can support 5Vin to -5Vout/0.3A ? I use webench to simulation ,but seems like it have duty issue

2. If TPS63710 can't support ,have any sync buck converter solution can do that ,just like TPS62136?

Hello,

TPS63710 has a 70% maximum duty cycle, that's why webench cannot simulate your system.

Many applications do not need -5.0Vout. If you do, you need to use an inverting buck-boost converter circuit such as this reference design:

Other inverting solutions like charge pumps exist but cannot provide more than 250mA output current.

If you have any other queries, please ask!

Thank you.

Best Regards,

Dorian

Hello,

I haven't heard back from you. Did you have a look at the reference design I mentioned?

Do you have any follow up questions regarding this matter?

Thank you very much!

Best Regards,

Dorian
