Infineon Technologies ICL8810 | Demoboard REF_ICL8810_LED_42W_PSR

42 W PFC-PSR-flyback reference design with ICL8810

Overview

TopologyFlyback Converter
Input voltage100-264 V
Switching frequency52 kHz
Output 154 V / 0.75 A
IC revision1.1

Description

Constant voltage primary-side regulated (PSR) topology is becoming more popular because of the lower cost compared with secondary-side regulated (SSR) topology. Components such as an optocoupler, a voltage reference and an error amplifier are no longer needed. It has excellent accuracy of ±3.5 percent in the range of 100 to 10 percent of the output power. Constant voltage PSR topology is the best solution for on/off LED drivers or LED drivers with minimum dimming levels down to 5 percent.

Features

  • Optimized as secondary-side-regulated (SSR) constant voltage (CV) output flyback controller, also well suited for PSR
  • Power factor (PF) > 0.9 and THD < 10% across a wide load range (AC input up to 277Vrms)
  • Integrated burst mode enables a very low stand-by power < 100mW
  • Critical conduction mode and quasi-resonant mode with smart valley hopping
  • External start-up circuit control signal
  • Comprehensive set of protections (OVP, OCP, etc.)

Typical applications

  • monitor up to 125W
  • LED lighting, Smart lighting
  • flat TV, all-in-one PC
  • Adapter & charger, LED driver and luminaires up to 125W.
