WEBENCH® Tools/LM43601: -5V Inverting Output Issue

AE104

Part Number: LM43601

Tool/software: WEBENCH® Design Tools

Hello,

I have designed -5V Inverter design based on Webench simulation. But Now I get +5V output. Could you take a look what the problem is?

Alpaslan,

Your IC GND is the -5 V output. Yout node at the red test ponit labeled "-5V" is the circuit ground.

In your schematic the point you have labeled "-5" should be connected to the system ground. That is you ground symbol and the input ground.

The net that is connected to the LM43601 grounds and the other components is the -5V output.

Please see the attached app note for more details.

When I connect to the AGND, which is main ground connected to the power supply, to the -5V node, I get 0 V.

I solved the problem, thank you. I probe the wrong points.
