Description
FA5500A/FA5501A are control ICs for a power factor correction converter using critical conduction mode of operation. This IC uses a CMOS device with high dielectric strength (30V) to implement low power consumption. These ICs contain compensated current sense comparator for light load and open/short protection at feedback (FB) pin. Compensated current sense comparator for light load keeps output voltage constant from no-load to full-load. Open/short protection at FB pin
stops output pulses when voltage divider to detect output voltage becomes fault.Features
• Low current consumption by CMOS process Start-up : 20µA(max.), Operating : 1mA(typ.)
• Drive circuit for connecting a power MOSFET directly
• Output peak current, source : 500mA, sink : 1000mA
• Compensated current sense comparator for light load
• Open/short protection at feedback (FB) pin
• Undervoltage Lockout
FA5500A: 11.5V ON / 9V OFF FA5501A:13V ON / 9V OFF
• Overvoltage protection
• Restart timer
• Package: DIP-8 / SOP-8 -
