Description: On-Bright confidential to ... OB3341S B uck LED Driver with High PF GENERAL DE SCRIPTION The OB3341S is a high power f actor, monolithic Buck regulator with a dvanced features to provide high effici ency control and high accuracy constant current output for LED lighting applic ations. OB3341S integrates a 2A MOSFET to decrease physical volume. It adopts constant on time control for power fact or correction (PFC), zero current detec tors (ZCD) to ensure quasi-resonant val ley turn-on for high efficiency operati on. OB3341S offers good protection cove rage including VCC under voltage lockou t (UVLO), VCC over voltage protection, cycle-by-cycle current limiting, over t emperature protection, COMP pin floa
