Overview

OB2009 is a high performance and highly integrated secondary side synchronous rectification controller used for secondary side rectification in switch mode power supply system. It drives 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, increase output current capability and efficiency, and simplify thermal design. It can support wide range of system output voltage 3V~28V.

Applications

AC/DC 3V~28V adaptors
Low voltage rectification circuits
Flyback low side synchronous rectification
Flyback high side synchronous rectification

Key features

Up to 150V VD and VIN pin high voltage tolerance
Self-supplying for operation without the use of an auxiliary winding
Suitable for DCM, QR and CCM operation
Soft gate drive for fast turn-off
Accurate secondary side MOSFET Vds sensing
Adaptive off time control effectively avoid the ring impact induced by parasitic elements
3A/1A peak current sink/source driver capability
VDD UVLO protection
