TPS659037: SMPS1/2 and SPMS4/5 with dual coupled inductors vs separate individual inductors

Part Number:TPS659037

Hi,

a customer is trying to use dual coupled inductors with SMPS1/2 and SMPS4/5 supplies to save board space. The EVM designs with AM5728 are using individual inductors.

Design:

AM5728 EVM

Is that design choice ok?

Regards,
