2.1.3.1 Input Connections

  • Prior to connecting the DC input source, set the current limit of the input supply to 0.1A maximum. Make sure the input source is initially set to 0V and connected to the VIN+ and VIN– connection points as shown in Figure 2-1. TI recommends an additional input bulk capacitor to provide damping when using long input lines.
  • Connect voltmeter 1 at the VIN+ and VIN– sense points to measure the input voltage. Instead of VIN+ at the input connector, use sense point TP5 near IC U1 to remove the voltage drop related to the EMI filter inductor.
  • Connect ammeter 1 to measure the input current. Use at least a 1-second aperture time to correctly measure the input current at light load in AUTO mode.
