7 / 8 page EnerChip™ CC Inductive Charging Evaluation Kit ©2012 Cymbet Corporation • Tel: +1-763-633-1780 • www.cymbet.com DS-72-14 Rev C Page 7 of 8 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. Reference Documents DS-72-03: EnerChip CC CBC3150 Data Sheet AN-1025: Using the EnerChip in Pulse Current Applications 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. |
