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.
