Part Number: LM2611

HI, team:

   Could you help select a DC/DC device could support 7vin, withstand voltage 18V，output -5.5V 0.15A .

   Hope small size not bigger than SOT23.

   Thanks.

    Hello Hailey,
    Thanks for reaching out to us via e2e.

    The LM2611 is the only dedicated CUK device we have.
    But it is possible to use a BUCK regulator like the LM5164Q to generate negative output voltages.
    Please see Webbench Designer how to connect it for that purpose:
    webench.ti.com/.../SDP.cgi

    The BUCK regulators are not supported by our team.
    So, if you have more questions about these devices, may I please ask you to start a new thread and use the part number LM5164Q, to make sure that it will get directed to the appropriate people.

    Thanks and regards,
    Harry
