Hi
Pls download below Calculator for circuit design

R150 should be 0 ohm if use TYPE3 ripple injection.
L6 220uH inductor saturation current should be >500mA
PCB layout looks good, you didn't show the ground…
Hello Vincent,
There is a quick calculator tool available for this device.
See link below

Also if efficiency is measured , input, output power and power loss can be easily calculated from knowing
Eff = Pout/Pin
Hope this…
