KA7525B Datasheet Power Factor Correction Controller

Manufacturer: Fairchild (now onsemi)

Overview: .fairchildsemi. Power Factor Correction Controller.

General Description

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 ponent count and low power dissipation.

Addition of internal current sense blanking (Internal R,C) eliminates the need for an external R/C filter.

Key Features

  • 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.
  • 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. K.
