ICL8820

Overview

Single-stage PFC flyback controller for constant voltage output

The ICL8820 is a single-stage PFC flyback controller for constant voltage output suitable for primary- and secondary-side regulation and allows for cost-optimized designs with exceptional PFC and THD performance. It comes with integrated burst mode and jitter function that enables stand-by power of <100 mW. The ICL8800 is the cost-effective basic variant. The ICL8810 has integrated burst mode.

Summary of Features

  • Integrated burst mode
