Linear LED Driver
The low cost 700V linear LED driver (220VAC powered) is a cap-less design, simple and with minimum count of external components.
An Example Chip :
Invention : New Power Regulation Scheme
Existing Linear LED Driver Lighting Solution has a problem of changing lighting power with changing AC Line Voltage. This problem makes Linear LED Driver Lighting Solution to be a very unpopular topology even though the overall BOM cost is attractively low.
