    Hello, all.

    Sorry but the remained message was deleted.

    We would like to use this device under the following conditions.

    Vin: 3.6 to 6V

    Vout: 48V

    Iout: 42mA

    Please let me clarify whether we could realize this configuration with TPS61170.

    If possible, please let me clarify which components on the Figure should be changed.

    Thank you for your information.

    Best regards,

    That circuit should be fine as is for your needs.  With your reduced output current needs, you can operate down to lower input voltages.

    Be sure to build and test it before you go to production.
