Fundamental Information
SC8913 EVM board is used for SC8913 which is featured with high efficiency, bi
-
direction operation (buck
charger/boost discharger), and integrated MOSFET. User can configure parameters flexibly through I2C
interface on the SC8913 EVM board. Besides, the charging/discharging function and all chip performance can
be evaluated with EVM board.
SC8913 EVM board parameters are as follow:
