OB2301W Datasheet High Performance Synchronous Rectifier

Manufacturer: On-Bright

Overview: On-Bright Electronics Co., Ltd. 0755-82584090/83587431 OB2301W High Performance synchronous rectifier.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

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 voltage down to 2V at constant current mode.

Key Features

  • Secondary-side synchronous rectifier optimized for 5V output system.
  • Suitable for DCM, QR operation.
  • Accurate secondary side MOSFET Vds sensing.
  • Low cost small size CC/CV mode support.
  • Up to 200kHz operation frequency.
  • 3A/2A peak current sink/source driver capability.
  • Output voltage over-shoot and under-shoot control.
  • Enhanced dynamic response with firing warning pulses scheme.
  • VDD UVLO protection.
