InnoSwitch-CP ICs use Power Integrations’ FluxLink technology which is said to optimise the effectiveness of output synchronous rectification, resulting in efficiency of 90%.
The ICs incorporate a suite of protection features including: OVP; output OCP with 3V auto restart; hysteretic thermal shutdown and line input overvoltage protection with brown-in/brown-out thresholds. They are also said to be compliant with safety and regulatory standards, including: 100% production HIPOT compliance testing equivalent to 6kV DC/1s; reinforced insulation; and isolation voltage testing to above 3,500Vac.
Two devices are available. The INN2214K IC delivers 15W output power for universal voltage chargers and adapters, while the larger INN2215K part delivers up to 22W for similar applications.
