Hi Dear,

Can the TPS40210 do cuk topology? Whether there are relevant reference designs

Hi Anna,

the TPS40210 can be used for a CUK but need some external logic to convert the negative FB voltage back to positive.

See this reference design for a possible implementation:

Hi Stefan,

If the input is 48V and the output is about -40V, using the TPS40210, can it be achieved through the CUK topology? How to choose the parameters of the peripheral circuit

Hi Anna,

CUK topology is not so often used therefore we do not have a quickstart calculcator for that but you can use the power stage designer:

POWERSTAGE-DESIGNER Design tool | TI.com

for that as well.

Best regards,

Stefan
