Hello!

Does anybody know, how many current consume typical design with TPS65131?

I made converter 3.3 -> +- 10.5 and have 75mA without load.

Is it right?

All other aspects work OK.

Thanks.

Hello Iurii Skrypka,

The typical input current for VI = 3.3 V and VPOS/VNEG = +/- 12 V is in the range of 47 mA +/- 5mA.
Your observation looks a bit too high. Is there anything else connected in your application that you maybe forgot?

Best Regards.
