NCP11377: PWM Switcher, Primary Side, High Voltage for Low Power Offline SMPS

内容: The NCP11377 offers a new integrated FET solution ...
  • The NCP11377 offers a new integrated FET solution targeting output power levels up to 12 W continuously in a universal−mains flyback application. Thanks to a Novel Method this new controller saves the secondary feedback circuitry for Constant Voltage and Constant Current regulation, achieving excellent line and load regulation without traditional optocoupler and TL431 voltage reference.
  • 特長
  • Integrated 650 V Power MOSFET with rds(on) of 3.2 Ω Typical @ 25°C - Low BOM counts eliminating secondary network
  • Constant Voltage Primary−Side Regulation < ± 5% - Low power standby
  • Internal Line FeedForward - High efficiency by quasi resonant switching and no secondary feedback power consumption
  • Quasi−Resonant with Valley Switching Operation - Thin SMD package for low profile converter
  • Optimized light load efficiency and Stand−by performance
  • Frequency clamp options
  • LFF and BO Feature on a Dedicated Pin
  • Cycle by Cycle Peak Current Limit
  • Output Voltage Under Voltage and Over Voltage Protection (UVP or OVP)
  • Secondary diode or winding Short−Circuit Protection
  • UVP Built−in Blanking Time to support 5000 μF Capacitive Load Capability
  • Cable Drop compensation adjustment
  • Wide Operation VCC range (up to 28 V)
  • Low Start−up current
  • CS & Vs/ZCD pin Short and Open Protection
  • Internal Temperature Shutdown
  • Internal and fixed Frequency Jittering for Better EMI Signature
  • These are Pb−Free Devices @ 25°C
  • アプリケーション
  • Low power AC/DC Adapters for Routers and Set−Top Box
