4.4.1 Input Voltage Monitoring (TP1, TP2)

The TPS40193EVM-001 provides two test points for measuring the voltage applied to the module. These test points allow the user to measure the actual module voltage without losses from input cables and connector losses. All input voltage measurements should be made between TP1 and TP2. To use TP1 and TP2, connect a voltmeter positive terminal to TP1 and negative terminal to TP2.
