FL7730 - Single-Stage Primary-Side-Regulation PWM Controller

Description

This highly integrated PWM controller, FL7730, provides several

Features

  • Compatible with Traditional TRIAC Control (No need to change existing lamp infrastructure: wall switch & wire).
  • Compatible with Non-Dimming Lamp Designs.
  • Cost-Effective Solution without Input Bulk Capacitor and Feedback Circuitry.
  • Power Factor Correction (PFC).
  • Accurate Constant-Current (CC) Control, Independent Online Voltage, Output Voltage, Magnetizing Inductance Variation.
  • Line Voltage Compensation for CC Control.
  • Linear Frequency Control for Better Effici.
