KA7525B  
Power Factor Correction Controller  
Features  
Description  
• Internal Start-up Timer  
• Internal Current Sense Blanking Which Eliminates the  
Need for an External R/C filter  
• Overvoltage Comparator Eliminates Runaway Output  
Voltage  
• Zero Current Detector  
The KA7525B provides simple and high performance active  
power factor correction. KA7525B 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 current sense blanking (Internal R,C) eliminates the  
need for an external R/C filter. Internal clamping of the error  
amplifier and multiplier outputs improves turn on overshoot  
characteristics and current limiting. Special circuitry has also  
been added to prevent no load runaway conditions. Output  
drive clamps limiting power MOSFET gate drive  
• One Quadrant Multiplier  
• Trimmed 1.5% Internal Bandgap Reference  
• Under Voltage Lock Out with 2.1V of Hysteresis  
• Totem Pole Output with High State Clamp  
• Low Start-up and Operating Current  
• 8-Pin DIP or 8-Pin SOP.  
independent of supply voltage greatly enhance the products  
practical application.  
Applications  
• Electronic Ballast  
• SMPS
