SOUTHCHIP SEMICONDUCTOR SC8905 DATASHEET DRAFT SOUTHCHIP CONFIDENTIAL, SUBJECT TO CHANGE SC8905 High Efficiency, Synchronous, Bi-Directional BuckBoost Charger Converter with Four Integrated MOSFET 1 Descriptions SC8905 is a synchronous buck-boost charger converter which also supports reverse discharging operation. Four switches are integrated to simplify the system design. SC8905 employs current-mode control and can support very wide input and output voltage range. It can support applications from 2.7V to 22V VBUS range. It is able to effectively manage charging for 2~4 cell batteries no matter input/output voltage is higher, lower or equal to battery voltage. When system needs to discharge from battery, the IC will deliver desired output from the battery.
