Quasi-Resonant IC

特性 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.
