1 Introduction
The BC100 is reference design/development kit that targets especially battery
charging. As the kit is general in nature it can be used to charge various battery
types, as long as the requirements to charging voltage and currents are within the
output range that the kit offers (1.2V to 38V, max 5A).
The kit can be used to develop applications such as battery chargers, battery
backup, Un-interruptable power supply, switch mode power supply and other.
