TPS55288: Buck-Boost Suggestion for 75 Watt Application

Hi there,

I'm looking for buck-boost IC for my application.

Parameters:18V-9V DC input, 15V DC / 5 ampers output. 

I checked the TPS55288 but I will not use the I2C function. So if you have any suggested part for the converter IC please let me know.

Thanks!
