SC8541
Single Cell High Efficiency 8-A Switched Capacitor Direct Charger
Introduce
SC8541 is a 97% efficiency, 8-A battery charging solution using a switched cap architecture. The switched cap architecture and the integrated FETs are optimized to enable a 50% cycle, allowing the cable current to be half the current delivered to the battery, reducing the losses over the charging cable as well as limiting the temperature rise in the application.
SC8541 adopts 56pin CSP 2.68mm X 2.68mm package.
