The OB2269CP is a current mode PWM controller designed for high-performance, low-standby power applications. It is optimized for offline flyback converters in AC/DC power supplies with power levels up to 20W. This controller provides efficiency improvements with its extended burst mode control, and it integrates comprehensive protection features such as over-voltage, over-temperature, and over-current protection with auto-restart capability.

The IC includes programmable PWM switching frequency, leading-edge blanking, and internal slope compensation, making it ideal for applications such as laptop power adapters, battery chargers, and open-frame power supplies. It is packaged in a SOP-8 package, ensuring compact design for surface-mount applications.

Key Features :

  • Extended Burst Mode Control: Minimizes power consumption during light or no-load conditions for high efficiency.
  • Low Startup and Operating Current: Ensures low standby power consumption, with startup current at 4µA and operating current at 2.3mA.
  • Complete Protection Coverage: Includes over-voltage, over-current, and over-temperature protection with auto-restart functionality.
  • Internal Slope Compensation: Enhances system stability and reduces sub-harmonic oscillation at high PWM duty cycles.
  • Leading-Edge Blanking: Reduces glitches on current sensing input and improves overall system reliability.
  • Programmable PWM Switching Frequency: Allows external control of the PWM switching frequency for design flexibility.
