Nanxin Technology has launched a new generation of PFC control chips, which can meet the requirements of medium and high-power chargers and adapters for power factor and input current harmonics. Equipped with core technologies such as no need for auxiliary windings, integrated THD optimization, and support for segmented output. Not only does it support multiple protection measures such as VFB overvoltage protection, VDD undervoltage protection, periodic current limiting protection, and ultra-high temperature protection, but it also supports second level independent overvoltage, undervoltage, and overcurrent protection. It can be widely used in USB-PD chargers, AC-DC adapters, LED drives, industrial power supplies, electric tools, and other fields.
