Quasi-Resonant IC FA5530/31/32

Features

FA5531 Block Diagram

• 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
