Dear all.

When a load current is light, does LMZ10503 continue a switching pulse?
If it doesn't continue switching pluse, please teach me point of variation.

I don't understand your question completely. The LMZ10503 has a negative current limit and no diode emulation mode. At light load the device continues switching in the CCM mode.

I understand, diode emulation mode.
Thank you.

LMZ10503 has no diode emulation mode except during startup. It will continue switching at the same frequency at light load. -Yang

The one I wanted to know is "the same frequency at light load".
Thanks,
