Power Integrations' LinkSwitch-4 CV / CC switch simplifies low-power CV / CC chargers, and its design is achieved by eliminating optocouplers and auxiliary control circuits. LinkSwitch-4 uses adaptive BJT drive technology to improve switching performance and efficiency. It also provides wider reverse-biased safe operating area (RBSOA) margin and can accommodate a variety of low-cost bipolar junction transistors (BJTs). Linkswitch-4 integrates a multi-mode PWM / PFM controller with quasi-resonant switching function to maximize efficiency, meet no-load below 30mW and maintain fast transients greater than 4.3V when the load changes from 0-100% response.
