OB2301W
High Performance synchronous rectifier
GENERAL DESCRIPTION
OB2301W is a high performance and tightly integrated secondary side synchronous rectifier for switch mode power supply system. 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. With its versatility and optimization, OB2301W can be used in various switch mode power supply topologies including secondary-side control topology and primary-side control topology. From the information on the secondary side of the isolation transformer, OB2301W generates a driving signal with de...
