Hi Pramanik,

We consider to use one DC/DC that input 28V and output +/-15V, if there are no promotion, please promote two bucks that output +15V and -15V, thanks.

Hi,
Please find the attached application note containing the generation of positive and negative power supply rail.

Create a Split-Rail Power Supply with a Wide Input Voltage Buck Regulator (Rev. A)

This device can support maximum current of 1.5A. This suits your application.

Thanks
