Description
3.1.1. Operating Voltage
The input operating voltages for DC-IN and USB are as follows:
 DC-IN 7.5V to 32V
 USB 5.0V
And the output voltage is as follows:
 Battery 4.2V(typical, at the end of charge)
DC-IN is the power supply input of the Fastrack Xtend ranging from 4.75V to 32V. In case the battery
accessory is used, the DC-IN voltage range should be restricted to 7.5V to 32V to ensure proper
battery accessory charging (charging is not effective below 7.5V). For more details about the Fastrack
Xtend operating voltage and current consumption, refer to document [2] AirLink FXT Series User
Guide.
