PMP11670: How to modify PMP11670 to 4.2A/5A total output (2.1A/2.5A each port) ?

Part Number:PMP11670

Hi,

May I know how to modify PMP11670 to 4.2A/5A total output (2.1A/2.5A each port) ? 

Current design is 2.0A (port1) +1.5A (port2).  

Since LM73605RNPR already outputs 5A, is changing TPS2549IRTERQ1 sufficient ? 



Thank you.
