OB2301W Overview
OB2301W is a high performance and tightly integrated secondary side synchronous rectifier for switch mode power supply system. It bines 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...
