ICL8800

Overview

Single-stage PFC flyback controller for constant voltage output

The ICL8800 is a single-stage PFC flyback controller for constant voltage output suitable for primary and secondary side regulation. ICL8800 enables cost-optimized platform designs with exceptional PFC and THD performance at full load and low load. The ICL8800 is the cost-effective basic variant. The ICL8810 has integrated burst mode. The ICL8820 adds built-in jitter.
