TPS65185 Power net / VEE_in

Hi,

The power net / VEE_in has  -16V on this node in my design but the specification say 16V, page 9.

This for me is very strange since I got the correct voltages on all power supplies.

Is this a typo or do I have something very strange in my design?

Best Regards
Johan

    Johan,

    You are right to have this voltage on this node. According to the absolute max ratings that pin has a voltage range from -20V to 0.3V, and the output of the DCDC2 is a negative 16V and is tied to the VEE_IN pin to supply the charge pump.
