TPS54225EVM-538: Trouble Configuring EVM to Output 5V

Part Number: TPS54225EVM-538
Other Parts Discussed in Thread: TPS54225

Hi Team,

My customer is having trouble getting the TPS54225EVM to output 5V. They changed R1 to 121kOhm, but no feedfoward cap has been added. Also, the inductor hasn't been changed.

They also changed R1 to 73.2K, 49.9K, and the EVM does output 2.5V and 3.3V. Can you help us understand why they are having trouble at 5V?

FYI - the input voltage is 12V. 

Thanks,
Mitchell
