LMR33640: Used for negative voltage

Part Number: LMR33640
Other Parts Discussed in Thread: LMZ14203

Hello,

I am using LMR33640 to generate a few positive voltages and LMZ14203 to generate a negative voltage, recommended by WEBENCH.

I'd like to know if is possible to use LMR33640 to generate the negative voltage, using the same topology, with the output connected to GND and the GND pin of the converter to be the output (negative voltage).

Regards,

Marius Raducanu
