BP3198
Description
BP3198 is a high precision PSR constant current LED driver with wall switch color dimming, and is suitable for 85Vac~265Vac universal input offline LED lighting.
BP3198 utilizes patent dimming control mode，by simple peripheral circuit, it can realize 2/3 kinds of fixed brightness dimming or 3 kinds of adjustable brightness dimming. In the 3 kinds of fixed brightness dimming，the output current presents three status 100%---60%--12%. In the 2 kinds of fixed brightness dimming, the output current presents 2 status 100%---8%.In the 3 kinds of adjustable brightness dimming, the output current of the second and the third status can be set by external resistors.
BP3198 work in inductor current discontinuous conduction mode，when it works in full brightness condition. Since adopting primary sense and feedback control technology, the secondary sense and feedback circuit is eliminated. The loop pensation ponents are also removed while maintaining stability overall operating...
