2.3 Power Supply

If the input current need to be measured, then an external VIN/VCC supply is recommended during evaluation.

  1. Connect the USB2ANY to the LP5813-12EVM using the ribbon cable.
  2. Connect a 1.8-5.5V external power supply to the VIN_EXT/VCC_EXT terminal (TP1 for LP5813/TP5 for LP5812) and connect the switching jumper (J2/J4) to VIN_EXT.
  3. If the user wants to evaluate LP5813 but disable the boost function, then please provide power supply from Vout instead of VIN.
  4. Plug the USB cable into the USB port on the computer.
