TPS548A20 - Inverting Buck Boost

Guru 20090 points
Other Parts Discussed in Thread: TPS548A20

Hello,

Can I use TPS548A20 as the following requirement?

Vin=13V
Vout=-6V

Could you please let me know the maximum sink, source current for this voltage?


I calculated the Iout based on the following application note.

Then the Iout(max) is about 9A for source.
Could you please let me know the sink case for inverting buck boost?

Best Regards,
Ryuji Asaka
