SC8571 is a 98.65% peak efficiency, 8-A battery charging solution using a switched cap architecture. The switched cap architecture and the integrated FETs are optimized for 50% duty cycle operation, 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. SC8571 adopts 80pin CSP 3.425mm X 4.151mm package.
