40W Demoboard with Isolated 0-10V Dimming Interface Single-Stage Multi-Mode Flyback Controller with PFC

Overview

TopologyFlyback Converter
Input voltage90-300 V
Output 145 V / 0.88 A
IC revision1.0

Description

This demo board design describes a 40 W LED driver; universal input 90-300 VAC, output voltage range 15-45VDC and isolated 0-10 V dimming for LED lighting applications.

Features

  • Single-stage flyback with power factor correction (PFC) and high-precision primary side-controlled constant current output.Excellent current accuracy of typ +/-3% acrosswide line/load to maintain a constant light output
  • Excellent line/load regulation over universal input and wide output within +3/-4%
  • Wide output voltage range (from 15 V – 45 V)
  • Integrated 600 V HV cell for fast startup and maintaining the efficiency across the wide input voltage
  • Low Bill Of Materials (BOM)
  • Intelligent thermal management
  • Quick design and variant handling supported by digital parameter configurability with .dp vision GUI.E.g. Output current setting, protections, temperature handling, startup & shutdown, dimming, power factor correction and operation fine tuning
  • The ICL8105 supports isolated 0-10 V dimming without the need for extra ICs. Extended dimming is supported down to 1% of the nominal load. Besides, the dimming curve is adjustable (linear / eyeadapted).Configurable voltage levels ensure that min and max current can always be achieved,making the application robust against dimmer & component tolerances

Typical applications

  • LED lighting
