Hi David,
You may download LM5166 Quick Start Calculator for your application design:

At PFM mode:
Input voltage range = 6 - 30V
Output voltage = 6V
Load current = 200mA
I_lim=0.5A
Fsw=600KHz at nominal 24Vi…
George,
Your SW waveform does not look good, but the probe should be DC coupled for that.
Looks like the pk-to-pk output ripple is the same for light load and medium load.
This implies your peak current is consistent in PFM and the converter operation…
Part Number: LM5166 Hi,
I have a problem with a DC/DC I used in a new design implementation regarding the ripple at output . Specifically we are talking about the LM5166XDRCR part. I have used a calculator from the TI website ( http://www.ti.com/tool/lm5166design…
