OB2269AP Current Mode PWM Controller IC - DIP-8 Package is a highly integrated current-mode PWM controller designed for offline AC/DC flyback power supplies. It provides programmable switching frequency, burst-mode operation for improved light-load efficiency, internal slope compensation, leading-edge current-sense blanking, and comprehensive protection functions. The IC is suitable for SMPS applications such as power adapters, battery chargers, set-top boxes, televisions, and other compact AC/DC power supplies. 

Features:

  1. Current-mode PWM control.
  2. Designed for offline AC/DC flyback converters.
  3. Externally programmable PWM switching frequency.
  4. Extended burst-mode operation for reduced standby power.
  5. Low startup current.
  6. Internal synchronized slope compensation.
  7. Leading-edge blanking on the current-sense input.
  8. Cycle-by-cycle over-current protection.
  9. Overload and over-temperature protection.
  10. VDD over-voltage protection and under-voltage lockout.
  11. Gate-drive output voltage clamped to protect the external MOSFET.
  12. Frequency-shuffling technology for improved EMI performance.
  13. DIP-8 through-hole package.
