TPS7B780x-Q1 Interfaces

  • VIN: 4.5V to 40V EVM power supply. Maximum input current is 600mA
    • J3 (VIN) / J13 (GND): Banana jacks J3 and J13 come pre-installed and are used to supply power to the EVM
    • J9: J9 does not come preinstalled. A terminal block can be installed at J9 as an alternate connection to supply power to the EVM
  • VOUT1: 2V to 40V output voltage from channel 1 (OUT1) of the TPS7B7802Q1. This connection can be used to apply a load current to channel 1 and monitor the output voltage of the channel. This connection is not used for the TPS7B7801Q1
    • J4 (VOUT1) / J10 (GND): Banana jacks J4 and J10 come pre-installed and can be used to connect a load to OUT1 of the TPS7B780x-Q1
    • J7: J7 does not come preinstalled. A terminal block can be installed at J7 as an alternate means to connect an external load to OUT1 of the TPS7B780x-Q1
  • VOUT2: 2V to 40V output voltage from channel 2 (OUT2) of the TPS7B780x-Q1. This connection can be used to apply a load current to channel 2 and monitor the output voltage of the channel. This is the only output channel on the TPS7B7801Q1
    • J14 (VOUT2) / J23 (GND): Banana jacks J14 and J23 come pre-installed and can be used to connect a load to OUT2 of the TPS7B780x-Q1
    • J20: J20 does not come preinstalled. A terminal block can be installed at J20 as an alternate means to connect an external load to OUT2 of the TPS7B780x-Q1
  • VIN_LDO: This connection is used to monitor input voltage directly at the input capacitor (C6) of the TPS7B780x-Q1
    • J1: J1 does not come preinstalled. An SMA connector can be installed at J1 to allow measurement of the input capacitor voltage.
  • LDO_OUT1: This connection is used to monitor output voltage for channel 1 directly at the output capacitor (C2) of the TPS7B780x-Q1
    • J2: J2 does not come preinstalled. An SMA connector can be installed at J2 to allow measurement of the output capacitor voltage for channel 1.
  • LDO_OUT2: This connection is used to monitor output voltage for channel 2 directly at the output capacitor (C11) of the TPS7B7802Q1. This is the only output channel on the TPS7B7801Q1
    • J12: J12 does not come preinstalled. An SMA connector can be installed at J12 to allow measurement of the output capacitor voltage for channel 1.
  • FB1: This connection is used to monitor the voltage from the feedback resistor divider for channel 1. This connection is not used for the TPS7B7801Q1
    • J8: J8 does not come preinstalled. A 0.1 inch (2.54mm) pitch 2 pin header can be installed at J8 if desired.
  • FB2: This connection is used to monitor the voltage from the feedback resistor divider for channel 2 of the TPS7B7802Q1. This is the only feedback divider for the TPS7B7801
    • J22: J22 does not come preinstalled. A 0.1 inch (2.54mm) pitch 2 pin header can be installed at J22 if desired.
  • Input Current Loop
    • I_IN: An AC/DC oscilloscope current clamp probe can optionally be connected through this loop to monitor input current to the TPS7B780x-Q1. This loop is sized to accommodate many common probes capable of accepting a 5mm conductor.
