Bipolar IC
For Power Factor Correction
s Description
FA5331P(M) and FA5332P(M) are control ICs for a power
factor correction system. These ICs use the average current
control system to ensure stable operation. With this system, a
power factor of 99% or better can be achieved.
FA5331P(M) is a 1st generation IC and FA5332P(M) is 2nd
generation IC which light-load characteristics are improved.
s Features
• Drive circuit for connecting a power MOS-FET(Io=±1.5A)
• Pulse-by-pulse overcurrent and overvoltage limiting function
• Output ON/OFF control function by external signals
• External synchronizing signal terminal for synchronous
operation with other circuits
• Undervoltage malfunction prevention function
• Low standby current (90µA typical) for simple start-up circuit
• 16-pin package (DIP/SOP)
±2% accuracy reference voltage for setting DC output and
overvoltage protection [FA5332P(M) only]
• When there is a possibility of light-load operation,
FA5332P(M) is suitable.

6. ON/OFF control input circuit
Figure 7 shows the ON/OFF control input circuit. If pin 12 is set
to the high level (enable), this IC outputs pulses from the OUT
pin. If pin 12 is set to the low level (disable), the internal bias
power (reference voltage) goes off and the IC current
consumption becomes about 1/10 that of its ON state. The
output level of pin 11 (CS for soft start) also goes low.
7. Output circuit
As Fig. 8 shows, pin 9 is configured as the high power terminal
(VC), independent of the IC power terminal (VCC). This pin
allows an independent drive resistance when the power
MOSFET is ON and OFF. If the drive resistances in the ON and
OFF states are Rg (on) and Rg (off), the following formulas can
be used to determine the total gate resistance
Rg:
Rg (on) = Rg1 + Rg2 ............................................. (9)
Rg (off) = Rg2 ..................................................... (10)
In the standby state, the output level of pin 8 is held low.
If the potential at the drain terminal of the power MOSFET
fluctuates, the gate-drain capacitance may drive the IC output
voltage at pin 8 to below 0. Once the voltage at pin 8 reaches
–0.6V, an unwanted current flows in the IC and a large abnormal
current flows in the output circuit when the output transistor is
turned on. To prevent this, connect a Schottky diode across the
gate and source of the power MOSFET.
