(1) See DS-72-03 EnerChip CC CBC3150 Data Sheet and DS-72-01 EnerChip CBC050 Data Sheet for complete specifica-
tions of the Cymbet components on the CBC51100 module included with CBC-EVAL-10B.
(2) Fluorescent (FL) light conditions. EnerChip state-of-charge >90%.
(3) Dependent on battery state-of-charge and load conditions. State-of-charge will affect average VIN. At 0% battery state-
of-charge, 2.6V < VIN < 3.1V, depending on load. At 100% battery state-of-charge, VIN will approach 5.2V at 700Lux.
(4) Continuous current for up to 1 minute with CBC51100 EnerChip module.
(5) For guidelines on adjusting the pulse current capability, see AN-1025: Using the EnerChip in Pulse Current Applications.

CBC-EVAL-10B Circuit Schematics
As a result of designing the CBC-EVAL-10B to be versatile and useful for designing to any number of operating
environments and system requirements, there are many circuit elements that will not be necessary for any
given CCEH implementation. The full schematic of Figure 6 depicts the CBC-EVAL-10B in its entirety. A simpler
and more often used embodiment is shown in Figure 7. In Figure 7, the provision for external batteries has
been removed, as has the circuitry required for external system control of the CBC3150 charge pump. The
schematic of Figure 7 is reduced to the essential elements necessary for implementing an energy harvesting-
based design using the CBC3150 circuitry and EnerChip batteries.
