PMP8454: PMP8454 with only 5V output

Part Number: PMP8454
Other Parts Discussed in Thread: PMP9175, TPS23753A, TPS23758EVM-080

Hello,

Is it possible to run the PMP8454 with only the 5V/1A output and still retain efficiency?  Essentially, just remove the 3.3V output and associated parts, and feed R18 to the 5V output?  The test data seems to show that this won't affect the efficiency.

Also, is there any data on minimum load and efficiency at minimum load?

Essentially, I am looking for a class 1, high efficiency, small minimum load, 5V design.


Regards,
