Enhanced EcoSmart® Integrated Off-Line Switcher with Advanced Feature Set and Extended Power Range. Converter Offline Flyback Topology 66kHz 8-PDIP-C.

Features:

  1. Lower System Cost, Higher Design Flexibility
  2. Multi-mode operation maximizes effi ciency at all loads
  3. New eSIP-7F and eSIP-7C packages
  4. Low thermal impedance junction-to-case (2 °C per watt)
  5. Low height is ideal for adapters where space is limited
  6. Simple mounting using a clip to aid low cost manufacturing
  7. Horizontal eSIP-7F package ideal for ultra low height adapter
  8. and monitor applications
  9. Extended package creepage distance from DRAIN pin to
  10. adjacent pin and to heat sink
  11. No heatsink required up to 35 W using P, G and M packages
  12. with universal input voltage and up to 48 W at 230 VAC
  13. Output overvoltage protection (OVP) is user programmable for
  14. latching/non-latching shutdown with fast AC reset
  15. Allows both primary and secondary sensing
  16. Line undervoltage (UV) detection prevents turn-off glitches
  17. Line overvoltage (OV) shutdown extends line surge limit
  18. Accurate programmable current limit
  19. Optimized line feed-forward for line ripple rejection
  20. 132 kHz frequency (254Y-258Y and all E/L packages) reduces
  21. transformer and power supply size
  22. Half frequency option for video applications
  23. Frequency jittering reduces EMI fi lter cost
