The OB2007MP from On-Bright Electronics is a highly integrated secondary-side synchronous rectification controller. It is engineered to drive an N-channel MOSFET, emulating a traditional diode rectifier to reduce voltage drop, heat dissipation, and improve efficiency in flyback converters. This controller is suitable for a wide range of system output voltages, from 3V to 21V, and supports multiple operating modes including discontinuous conduction mode (DCM), quasi-resonant mode (QR), and continuous conduction mode (CCM).
Key features include a high VD pin voltage tolerance of up to 180V, self-supplying operation without an auxiliary winding, and soft gate drive for fast turn-off. The OB2007MP utilizes accurate secondary-side MOSFET Vds sensing and adaptive off-time control to mitigate ring impacts from parasitic elements. It offers a peak current driver capability of 3A/2A (sink/source) and includes VDD UVLO protection.
This controller is offered in a compact SOT-23-6 package, making it suitable for space-constrained applications such as AC/DC 3V-21V adaptors and other low voltage rectification circuits. Its design simplifies thermal management and increases output current capability and overall system efficiency.
The OB2007MP supports a system output voltage range of 3V to 21V.
The VD pin has a high voltage tolerance of up to 180V.
The VDD supply voltage range is from 4.5V to 9.5V.
The OB2007MP is suitable for discontinuous conduction mode (DCM), quasi-resonant mode (QR), and continuous conduction mode (CCM).
The OB2007MP is offered in a SOT-23-6 package.
The minimum packaging quantity is 3000 units.
