    Hi Nick,

    You can produce a negative output voltage with a buck using an inverting buck boost configuration. Please see this user's guide with this device in an inverting buck boost mode EVM. This guide also has references to the general theory and calculations that go into this process.

    The recommended operating junction temperature conditions for this part are -40 C to 125 C per datasheet section 5.3. This part is not recommended to be operated at 150 C.

    Thank you,

    Joshua Austria
