Can LMR14050 output 12V/3A?

Hello,

     I am designing the buck with LMR14050 .My question is :

  • Input: 24V
  • Output :12V/3A

       I can not obtain the stable output. Please see below waveform:

Figure 1 Input 24V-Ouput 12V/2A-RIpple Voltage 2.6V(Peak -Peak)

Figure 2 Input 24V-Ouput 12V/2A-SW node

The circuit is below:

Please give your advice,

Thanks

Devin
