LP8866-Q1: Usage of coupled inductor

Part Number: LP8866-Q1

Hi Expert team,

I want to use a coupled inductor in SEPIC configuration of LP8866-Q1 backlight driver. In datasheet or on e2e I did not find any related topic to understand the requirement for this. is there anything I need to take care in schematic as well as in layout while using coupled inductor? Please help.

The basic requirements are

Vout= 35.2V

Vin(min)= 9V

Iout = 780mA

Fsw = 1818KHz
