Datasheet Summary
Description
BP3108 is a primary side regulation (PSR) controller with triac dimming designed for high brightness LED driver. It’s extremely suitable to be used in flyback converter operating in worldwide voltage range.
BP3108 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 pensation circuitry. This control method also achieves excellent line and load regulation.
BP3108 integrates the triac dimming control circuit internally.Few external ponents are required to achieve wide triac dimming range and good dimming effect without visible flicker.
