Buck converter with negative output possibility

Hello. I’m looking at some of your buck converters that have the possibility to provide a negative output as well. In particular my project requires that starting from a Vin of +12 generate a Vout of 5V 12A, 3V3 12 Aand -12V 3A using the same device for each branch.


Hello Antonio,

MPS typically does not carry negative buck converters. Instead, you can create an inverting buck-boost using a normal buck converter. A consideration in choosing the correct buck converter is to have the Vmax of the part be greater than Vin+|Vout|. One such part is the MP8774H | 12A, 18V Sync Buck

Thank you,
