Part Number: LM2611

Hi,

Could you review the schematic for -12V output from 12V?

current is 5mA.

Additionally, what component has to be changed for 50mA current?

Now R16 is 87.5kOhm.

Thanks.

Hello David,

The schematic seems to be OK. What happens if you increase the load?

What is the current rating of the inductors?

Best regards,

Brigitte
