LMZ21701: :

Part Number: LMZ21701
Other Parts Discussed in Thread: TPS62150

Good morning,

I am planning to use LMZ21701 on my design to generate 4 different power rails. 

With TI Webench tool I can't do simulation below 300mA load values. 3 of may voltage rail loads are a round 300mA so they are okay. 

One of my application requires only 30mA continuous from 1V2 voltage rail. My input voltage to LMZ21701 is 5V. 

I see from the datasheet that it is doable. There is also a PWM and PSM modes.

If 30mA falls into PSM mode, then is there going to be a pulse skipping in order to generate the needs? Pulse skipping may have bad impact to EMI?
