5.2 Power Up

To verify the startup behavior, connect the oscilloscope to the evaluation module:

  • Channel 1 – input voltage (test point label VIN)

  • Channel 2 – output voltage (test point label VOUT)

  • Channel 3 – GATE voltage (test point label GATE)

Set the load to 200 mA, trigger to channel 1 rising, and turn ON the power supply. Startup behavior of LM74502EVM is captured in Figure 5-2.
