1. 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.
2. 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
