EnerChip™ CC Inductive Charging Evaluation Kit
Vmax = final voltage to which the capacitor must be charged prior to delivering the next current pulse
Vmin = initial voltage on the capacitor when charging begins
Vchg = applied charging voltage on the capacitor
Electrical resistance of the energy storage device varies according to temperature and state-of-charge as
described above. Worst-case conditions are often applied to the calculations to ensure proper system operation
over temperature extremes, aging of the energy storage device, capacitance tolerance, etc.
Circuit Board Alterations
The CBC-EVAL-11 receiver board is designed to permit the user to separate the planar inductor from the
remainder of the circuitry, allowing the user to attach another inductor, such as a coil. The planar inductor may
be electrically isolated from the remainder of the circuit by cutting the trace connecting the inductor to the
circuit. If physically separating the inductor from the circuit, be careful to saw cleanly between the inductor and
the circuit and avoid damaging traces and components on the board. When sawing, be careful to not flex the
circuit board; doing so can fracture the solder joints attaching the larger components to the board - specifically
the 1000µF tantalum capacitor and the CBC3150 EnerChip in the surface mount DFN package. To minimize
stress on the solder joints, it is recommended that the board be cut cleanly through rather than scoring and
breaking the board apart.
The receiver board also has provision for connecting another coil and capacitor to facilitate the use of an LC
tank circuit other than the one provided. Solder pads are provided for a 0606 size chip capacitor. Adjacent to
those pads are plated vias in the board for inserting and soldering the ends of a user-supplied inductor.

Important Notice
Cymbet provides the evaluaiton kit under the following conditions:
This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR
EVALUATION PURPOSES ONLY and is not considered by Cymbet to be a finished end-product fit for general
consumer use. It generates, uses, and can radiate radio frequency energy and has not been tested for
compliance with the limits of computing devices pursuant to part 15 of FCC rules, which are designed to
provide reasonable protection against radio frequency interference. Operation of this equipment in other
environments might cause interference with radio communications, in which case the user at his own expense
will be required to take whatever measures might be required to correct this interference.
Persons handling the product(s) must have electronics training and observe good engineering practices. As
such, the goods being provided are not intended to be complete in terms of required design-, marketing-, and/
or manufacturing-related protective considerations, including product safety and environmental measures
typically found in end products that incorporate such components or circuit boards. This evaluation kit does
not fall within the scope of the European Union directives regarding electromagnetic compatibility, restricted
substances (RoHS), recycling (WEEE), FCC, CE or UL, and therefore might not meet the technical requirements
of these directives or other related directives.
