2.1.1 Test Points

See Figure 3-2 for typical test setup. The functions of the test point connections are:

  • VIN_EMI — Input supply to EVM.
  • GND_EMI — Ground connection for the input supply.
  • VIN — Input supply to the IC. Can be connected to a digital multimeter to measure the input voltage after EMI filter.
  • VOUT — Output voltage test point of EVM. Can be connected to a desired load.
  • GND — Ground test point.
  • PG — This test point is connected to the PGOOD pin from the IC.
  • SYNC — This test point can also be connected to an external clock to synchronize the IC.
  • GND— This test point represents the analog ground test point and is connected to the ground plane.
