Buck-Boost Charger

Southchip not only lunched the world's first buck-boost charging/discharging bidirectional smart charger controller, and we also provides users with the most extensive range of buck-boost charger portfolios in the industry. The Southchip buck-boost chargers support the bi-directional operations of stepping up or down voltages, and the single chip can easily meet the charge and discharge management of the battery. The chargers can support wide operation voltage from 2.7V to 36V, and can support 60W~100W power conversion with external power MOSFETs with up to 98% efficiency, supporting USB PD applications effectively.
