TPS54260-Q1: Similar IC with higher current rating 4 - 6 A / better EMI/EMC ratings

We are using TPS54260-Q1 Automotive qualified DC DC converters in our existing design.

But we do face EMI/EMC issues on 2 layer PCB boards.

So we require an IC same as of TPS5420-Q1 but with higher EMI/EMC rating that will pass EMI/EMC testings on 2 layer PCB boards.

Or kindly provide pcb layout of any boards that use this IC for better EMI compatibility.

Also we require an IC of same specifications but with higher current rating 4 - 6 A.

Required conditions for design

Vin = 8-32V

Vout = 6.8V

Iout = 2.5 A / 4 -6 A

Switching frequency = 750 Khz (generally)

Requirement: power supply for interfacing vehicle level inputs to microcontroller
