ICL8810
概要
Single-stage PFC flyback controller for constant voltage output
The ICL8810 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 for stand-by power <100 mW suitable for battery charging and smart lighting. The ICL8800 is the cost-effective basic variant without burst mode. The ICL8820 adds built-in jitter.
