What is the difference between isolated and non-isolated drives

[Summary description] Non-isolation refers to the direct electrical connection between the output terminal and the input terminal. The lack of transformer isolation in non-isolated circuits means that LEDs are more susceptible to damage from surges from the AC supply due to load switching transients or primary-side interference. Isolated driver: 1. Flyback converter topology 2. More expensive 3. High efficiency 88% Non-isolated driver: 1. Buck or buck-boost topology 2. More efficient 3. Less heat dissipation due to insulation

Non-isolated means that the output terminals and input terminals are directly electrically connected. The lack of transformer isolation in non-isolated circuits means that LEDs are more susceptible to damage from surges from the AC supply due to load switching transients or primary-side interference.

Isolated driver: 1. Flyback converter topology 2. More expensive 3. High efficiency 88%

Non-isolated drivers: 1. Buck or buck-boost topology 2. More efficient 3. Insulation leads to less heat dissipation
