Product Overview

The MC33262PG is an active Power Factor Controller specifically designed for use as a pre-converter in electronic ballast and in off-line power converter applications. This integrated circuit features an internal start-up timer for stand-alone applications, a one quadrant multiplier for near unity power factor and zero current detector to ensure critical conduction operation, trans-conductance error amplifier and quick-start circuit for enhanced start-up, trimmed internal band gap reference, current sensing comparator and a totem pole output ideally suited for driving a power MOSFET. Also includes protective features consisting of an overvoltage comparator to eliminate runaway output voltage due to load removal, input under-voltage lockout with hysteresis, Cycle-by-cycle current limiting and multiplier output clamp that limits maximum peak switch current, an RS latch for single pulse metering and a drive output high state clamp for MOSFET gate protection.
  • Over-voltage comparator eliminates runaway output voltage
  • Internal start-up timer
  • One quadrant multiplier
  • Zero current detectors
  • Trimmed 2% internal band gap reference
  • Totem pole output with high state clamp
  • Under-voltage lockout with 6V of hysteresis
  • -40 to 105°C Extended operating temperature range
