Hi,

Below is the schematic of LT3471 for you reference. LT3471 only have 11pins, but TPS65131 is 24pins. I can't see any benefit competing with LT3471. do you have further recommendation? +-15V is a common need in my customer. thanks.

Hello,

To my knowledge, TPS65130/131 is the only split rail converter that meets your specification (5Vin, +/-15Vout). I am not finding any other devices under split rail converters.

Kind Regards,
