Description BP3105 is a high precision primary side regulation (PSR) controller designed for high brightness LED driver.
It’s extremely suitable to be used in flyback converter operating in worldwide voltage range.
BP3105 works in discontinuous inductive current mode.
The patented control method dramatically saves the system cost and size by eliminating all secondary feedback circuitry and loop control compensation circuitry.
This control method also achieves excellent line and load regulation.
BP3105 integrates high precision current sense circuitry, which achieves ±3% LED current accuracy.
BP3105 offers rich protection features including LED short/open circuit protection, over-temperature ...
