FA5502M Datasheet

Power Supply Control IC


FA5502P/M is a control IC for a power factor correction system. This IC uses a CMOS device with high dielectric strength (30V) to implement low power consumption. This IC uses the average current control system to ensure stable operation. With this system, a power factor of 99% or better can be achieved. 

• Low current consumption by CMOS process
• Stand-by : 3µA(max), Start-up : 30µA(max), Operating : 4mA(typ)
• Good regulation of PFC output voltage from no-load to full-load
• Drive circuit for connecting a power MOSFET(IOUT= ±1.5A)
• Pulse-by-pulse overcurrent and overvoltage limiting function
• ±2% accuracy reference voltage for setting DC output and overvoltage protection
• Output ON/OFF control function by external signal
• External synchronizing input pin for synchronous operation with other circuits
• Undervoltage lockout function (ON:16.5V, OFF:8.9V)
• 16-pin package (DIP/SOP)
