OB3341S Buck LED Driver with High PF GENERAL DESCRIPTION The OB3341S is a high power factor, monolithic Buck regulator with advanced features to provide high efficiency control and high accuracy constant current output for LED lighting applications. OB3341S integrates a 2A MOSFET to decrease physical volume. It adopts constant on time control for power factor correction (PFC), zero current detectors (ZCD) to ensure quasi-resonant valley turn-on for high efficiency operation. OB3341S offers good protection coverage including VCC under voltage lockout (UVLO), VCC over voltage protection, cycle-by-cycle current limiting, over temperature protection, COMP pin floating protection and LED open/short protection. OB3341S is provided with DIP8 package.
