1. Efficiency measured from DC input to the transmitter to DC output of the receiver. The BQ500210EVM-689

TX was used for these measurements. Measurement subject to change if an alternate TX is used.

2. Total droop experienced at the output is dependent on receiver coil design. The output impedance must be

low enough at that particular operating frequency in order to not collapse the rectifier below 5 V.

3. On-the-go mode is enabled by driving EN1 high. In this test, the external PMOS is connected between the

output of the BQ51013B device and the AD pin; therefore, any voltage source on the output is supplied to the

AD pin.
