Power Factor Correction ICs


  • Status:Available

The FA5502M is a control IC for power factor correction converters. It achieves low power consumption by using a high-voltage CMOS process. Since it uses an average value current control method, it is capable of stable operation and can easily achieve a power factor of 99% or higher. In addition, it can control the DC output voltage over a wide range of loads from the rated load down to no-load.


  • Achieves low power consumption by using a high-voltage CMOS
    1. Standby of 3 μA( max), startup of 30 μA(max), 4 mA (typ) during operation
  • Capable of controlling the DC output voltage even with no load
  • Built-in drive circuit that enables the direct connection of a power MOSFET (output peak current: ±1.5 A)
  • Built-in pulse-by-pulse type overcurrent and overvoltage limiting circuit
  • Enables setting of DC output voltage and overvoltage limit with ±2% precision voltage reference
  • Capable of ON/OFF control using an external signal
  • Includes an external synchronization pin, enabling synchronized operation with other circuits
