EnerChip CC CBC3112
Real-Time Clock Application Circuit
The EnerChip CC as depicted in Figure 10 is a typical application circuit in a 3.3 volt system where backup and
power switchover circuitry for a real-time clock device is provided.

Adding Power and Energy Capacity with Parallel EnerChips
In some applications, additional EnerChip capacity might be needed. The schematic in Figure 11 shows how
multiple EnerChips can be supported in parallel by a single EnerChip CC CBC3112. Note that C
should be
FLY
increased by 0.1µF for every additional EnerChip.
