Quasi-Resonant IC

FEATUREs
•Internalstart-up circuit with 500V rating and low
  frequency operation achieves140mW input at no load.
•Small Output Capacitance : Linearly reduced
  frequency for lighter load causes small ripple voltage.
•Suitable for Low Noise andHigh Efficiency about 90%
•Line-up of 3 types for maximum frequency and OLP
  5530: 65kHz max.,16Vmax.-VCC,Auto-restart OLP
  5531:130kHz max.,28Vmax.-VCC,Auto-restart OLP
  5532:130kHz max.,28Vmax.-VCC,Timer-Latched OLP
•High ability of driving Power MOSFET ( High / Low side : 17 ohm / 3.5 ohm ) : available to 200W output
•Vcc rating 28V allows noseries regulator for auxiliary winding to clamp Vcc voltage for FA5531/32.
•1ms Fixed Soft Start time
•Timer Latched Over-Voltage Protection of 16V/28V Vcc
•8 pins package ( DIP/SO )
  Usage : Notebook PC, LCD Monitor, LCD-TV etc.
