Description

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.

Features

• 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)
