It combines a much lower voltage drop N-channel MOSFET to emulate the traditional diode rectifier at the secondary side of Flyback converter, which can reduce heat dissipation, increases output current capability and efficiency and simplify thermal design. OB2301W can support low system output voltage down to 2V at constant current mode. It is suitable for multiple mode applications including discontinuous conduction mode and quasi-resonant mode.
