Description

This reference design is a universal input, 48V, 10.4A constant current (CC), constant voltage (CV) charger for e-bike applications. The reference design achieves 91.5% end-to-end peak efficiency with a 110Vac input, and 93.50% end-to-end peak efficiency with a 230Vac input. This design includes fan control and charging status indication based on output current. This reference design uses the UCC28180, UCC256603, UCC28910, and TL103W devices.
