TPS62150: 1.What is operation condition for PWM & PSM? 2.What is effect of different switching frequency(1.25MHz & 2.5MHz)?

Dear TI,

As title ,

1.What is TPS62150 operation condition for PWM & PSM? 

I think the condition is that the output current becomes smaller than half the inductor ripple current.

Is the description correct?

2.What is effect of different switching frequency(1.25MHz & 2.5MHz)?

I think if TPS62150 running with the low-frequency setting, inductor value should be increase. 

Is the description correct?

Have any else effect? 

Thanks a lot & best regards,

Ronald
