10 Power Supply Recommendations

These devices are intended to be operated within the ranges shown in the Recommended Operating Conditions. Because the system involves a loosely coupled inductor set up, the voltages produced on the receiver are a function of the inductances and the available magnetic field. Ensure that the design in the worst case keeps the voltages within the Absolute Maximum Ratings.
