Test Points

The test points on the board can be used for connecting to the input of a power supply and output load for the EVM. See Figure 1-1 for typical test setup. The functions of the test points connections are:

  • VIN_EMI — Input supply to EVM including an EMI filter. Connect to a suitable input supply. Connect at this point for EMI test.
  • GND_EMI — Ground connection for the input supply
  • VIN — Input supply to the IC. Can be connected to DMM to measure input voltage after EMI filter.
  • VOUT — Output voltage test point of EVM. Can be connected to a desired load.
  • GND — Ground test points
  • EN — This test point is connected to the EN pin. By default, there is a pullup resistor R1 (RENT) to VIN to enable the IC.
  • PGOOD — This test point is connected to the PGOOD pin from the IC. Can be tied to an external supply through a pullup resistor or left open.
  • RT — In a RT trim part, this test point is connected to the RT pin of the IC.
