I understand that in light loading mode, efficiency is high even under a light load. I'd like to know why that is the case, and the conditions for switching to light loading mode.
- During light loading, switching can be skipped (switching is made sparse) to improve efficiency. When the load current is roughly 1/2 or less of the inductor ripple current IL, skipping action is begun.
