2.5.2 Load Transient Circuit Interfaces

  • VDD: load transient circuit 5V supply. Accepts a supply voltage between 4.75V and 5.4V at 100mA
    • J37 (VDD) / J41 (GND): Connect an external 5V power supply to these connections to power the onboard load transient circuit.
  • Load EN: 0V to 3.3V square wave trigger input for the load transient circuit. Applying 0V disables the transient load. Applying 3.3V enables the transient load. Input voltage on this connection must not exceed VDD.
    • J38: J38 does not come preinstalled. An SMA connector must be installed at J38 to allow the load transient circuit to be used.
  • EXT DC LOAD: External DC load resistor or electronic load connection.
    • J34: J34 does not come preinstalled. If using the load transient circuit, a terminal block can be installed at J34 to connect an external DC load for load transient testing.
  • V_LOAD: Measurement point for voltage drop across optional load resistor R20
    • J33: The added inductance from the load transient current loop can limit transient rise times. For very fast transient tests, J33 is provided to measure voltage drop across load resistor R20 and calculate load current.
  • VOUT2 Load Transient Current Loop: Measurement loop for current from VOUT2 into the load transient circuit
    • IOUT_2: An optional AC/DC oscilloscope current clamp probe can be connected through this loop to monitor transient output current from channel 2. This loop is sized to accommodate many common probes capable of accepting a 5mm conductor.
