General Description

The SA7527 provides simple and high performance active power factor correction.

The SA7527 is optimized for electronic ballasts and low power and high-density power supplies which require minimum board size, reduced external ponents and low power dissipation.

Because the R/C filter is included in the current sense block, the external R/C filter is not necessary.

Key Features

  • Internal start-up timer.
  • Internal R/C filter eliminates the need for an external R/C filter.
  • Very precise adjustable output over voltage protection.
  • Zero current detector.
  • One quadrant multiplier.
  • Trimmed 1.5% internal band gap reference.
  • Under voltage lockout with 3V of hysteresis.
  • Totem pole output with high state clamp.
  • Low start-up and operating current.
  • 8-pin DIP or 8-pin SOP.
  • Electronic ballast.
  • SMPS Device SA7527 SA7527S Package.
