High Efficiency 8-A Switched Capacitor Direct Charger with SCP/UFCS PHY Integrated
SC8546 is a high efficiency 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.
SC8546 adopts 36pin CSP 2.765mm X 2.695mm package.
