PQ8541

Single Cell High Efficiency 8-A Switched Capacitor Direct Charger

PQ8541PQ8541

PQ8541

PQ8541 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. PQ8541 adopts 56-pin CSP 2.68mm x 2.68mm package.
