Overview
Quasi-Resonant IC FA5530/31/32 Features Features • Internal start-up circuit with 500V rating and low frequency operation achieves 140mW input at no load.
• Small Output Capacitance : Linearly reduced frequency for lighter load causes small ripple voltage.
•Suitable for Low Noise and High 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 no series 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.
