5V In to 15V, 350mA Out @ 85 deg. C Power Supply Solution

Hello,

For a card featuring multiple AD5755-1 and ADAS3022 converter as well as OPAMPs, I'm looking for a 5V In to +15V 350mA Out analog power supply solution (operating temperature up to 85 deg. C, air cooled) (low ripple)

Any proven/verified/recommended circuits? Any suggestions?

Thanks

  • Hi,

    yes, I've already done that of course.

    I was just hoping for an already verified reference design.

    I mean many IC parts (A/D, D/A, OPAMP etc.) still have a recommeded analog power supply of +/-15V. But most of the converter data sheets are showing 12V example circuits instead of 15V.

    Additionally we would like to have an I temperature part (not an E part).

    I have narrowed it down to LT3477, LT3959 or LTM4661 so far. Still running simulations.

    Thanks
