Test Setup
6.4 Load Dump
The procedure for load dump is as follows:
• Set up the test bench as described in Section 6.2 .
• Power TX with 19 V.
• Provide a load dump from 10
Ω
or 500 mA (if using a current source load) to no load (high
impedance).
• Monitor load current, rectifier voltage, and output voltage as shown in the following illustration.

6.5 V-Adapter Input
The procedure for external adapter (wired adapter) testing is as follows:
• Set up the test bench as described in Section 6.2 .
• Power TX with 19 V
• Apply a 6-V V-adapter input voltage.
• Monitor load current, rectifier voltage, output voltage, and V-adapter voltage as shown in the following
illustration.
