3.2 Bench Setup

Follow the connection procedure below and Figure 3-1 can be used as a reference.

  • Make sure all the output of the function generator, and voltage source are off before connection.
  • Function generator Ch-A channel applied on IN_IN.
  • Power Supply:
    • Power supply #1: positive node connected to input of DMM #1 and DMM #1 output connected to test point marked as VCC, negative node of Power Supply #1 connected directly to test point marked as GND.
    • Power supply #2: negative node connected to OCP_IN and positive node connected to GND or GND_IO (whichever is more convenient), this makes it so OCP_IN sees -5V­, not 5V.
  • Oscilloscope:
    • VDD Signal: Connect oscilloscope Ch-1 probes to test points marked as VDD to GND, smaller measurement loop is preferred.
    • IN Signal: Connect oscilloscope Ch-2 probes to test points marked as IN to GND, smaller measurement loop is preferred.
    • OUT Signal: Connect oscilloscope Ch-3 probes to test points marked as GATE to GND, smaller measurement loop is preferred.
    • FLTb Signal: Connect oscilloscope Ch-4 probes to test points marked as EN/FLT to GND, smaller measurement loop is preferred.
