Description

The AP1682E is a high performance AC/DC universal input Primary Side Regulation Power Factor Controller for LED driver applications.

The device uses Pulse Frequency Modulation (PFM) technology to regulate output current while achieving high power factor and low THD.

The AP1682E provides accurate constant current (CC) regulation while removing the opto-coupler and secondary control circuitry. It also eliminates the need of loop compensation circuitry while maintaining stability. The

AP1682E achieves excellent regulation and high efficiency, yet meets the requirement of IEC61000-3-2 harmonic standard.

The AP1682E features low start-up current, low operation current and high efficiency. It also has rich protection.

Feature(s)

  • Primary Side Control for Output Current Regulation Without Opto-coupler and Secondary CV/CC Control Circuitry
  • Low Start-up Current
  • High Power Factor and Low THD for Universal Input Range
  • Tight CC Regulation Performance for Universal Input Mains Voltage Range
  • Eliminates Control Loop Compensation Circuitry
  • Built-in Acceleration Start
  • Open-load and Reload Detection
  • Over Voltage and Short Circuit Protection
  • Over Current Protection
  • Cost Effective Total PFC LED Driver Solution

 

Application(s)

  • Single Stage Power Factor Correction Power Supply for LED
  • Lighting
