FL7734 Datasheet Single-stage Primary-side-regulation Pwm Controller

Manufacturer: Fairchild (now onsemi)

Overview: FL7734 — Single-Stage Primary-Side-Regulation PWM Controller for PFC and Phase Cut Dimmable LED Driving November 2014 FL7734 Single-Stage Primary-Side-Regulation PWM Controller for PFC and Phase Cut Dimmable LED.

General Description

The FL7734 is a highly integrated PWM controller with advanced Primary-Side-Regulation (PSR) technique to minimize ponents for low power LED lighting solutions.

Using the innovative TRUECURRENT® technology for tight constant-current control, it enables designs with constant-current (CC) tolerance of less than ±1% in the wide line voltage range to meet stringent LED brightness requirements.

FL7734 can operate with all types of phase cut dimmers.

Key Features

  • Excellent Dimmer Compatibility by Active Dimming Control.
  • Programmable Dimming Curve and Input Current Management.
  • Constant LED Current Regulation in Large Phase Angle Range.
  • Cost-Effective Solution without Input Bulk Capacitor and Feedback Circuitry.
  • Accurate Constant-Current (CC) Control, Independent on Line Voltage, Output Voltage, Magnetizing Inductance Variation.
  • Power Factor Correction (PFC).
  • Fast Startup utilizing Bleeding Circuit.
  • Open-LED Protect.
