FAN7527  
Power Factor Correction Controller  
Features  
Description  
• Internal Startup Timer  
• Internal R/C filter which eliminates the Need for an  
External R/C filter  
• Overvoltage Comparator eliminates Runaway Output  
Voltage  
• Zero Current Detector  
The KA7527 provides simple and high performance active  
power factor correction. KA7527 is optimized for electronic  
ballast and low power, high density power supplies requiring  
a minimum board area, reduced component count and low  
power dissipation. Addition of internal R/C filter eliminates  
the need for an external R/C filter. Internal clamping of the  
error amplifier and multiplier outputs improves turn on over-  
shoot characteristics and current limiting. Special circuitry  
has also been added to prevent no load runaway conditions.  
The output drive clamping circuit limits overshoot of the  
power MOSFET gate drive Independent of supply voltage,  
so that it greatly enhance the system reliability.  
• One Quadrant Multiplier  
• Trimmed 1.5% Internal Bandgap Reference  
• Under Voltage Lock Out with 5V of Hysteresis  
• Totem Pole Output with High State Clamp  
• Low Startup and Operating Current  
• 8-Pin DIP or 8-Pin SOP  
• Over Voltage Protection Function ( Soft OVP, Dynamic  
OVP, Static OVP )  
8-DIP  
Applications  
• Electronic Ballast  
• SMPS
