Our customer is studying with your ADD5203 in exchange for ADD5211 past you recommended.
As for your "DC current dimming" function of page-12 on you datasheet,
Does this means 100%-80%- 60%,,,,,(reduce)can do, but 0%-20% 40%-,,,,,,,(growth) cannot do?
If it is driven by current 100%, then what is the generation of heat? less than junction temperature without heat sink?
