2.1 Power Requirements

The IO-Link Master BoosterPack™ is powered from an 24-V supply connected to either the DC Power Jack (2.0
mm I.D x 6.5 mm O.D max) J6, or the 2-pin screw terminal block J7.

To avoid damaging the inputs of the LaunchPad, the BOOSTXL-IOLINKM-8 board should not be powered prior
to the LaunchPad. The Shutdown (SHDN) pin of the TPS26631 eFuse device can be used disconnect the 24-V
supply to the board when the LaunchPad board is not powered by using the LaunchPad 3V3 supply voltage to
control the shutdown (SHDN) pin.
The BOOSTXL-IOLINKM-8 board can be used when disconnected from the LaunchPad board such as when
doing certain physical layer testing with test equipment. In this configuration the Shutdown (SHDN) pin of the
TP26631 eFuse should be connected to the external 24-V supply so that the board is powered when the 24-V
supply is active.
The Digital IO voltage level of 3.3 V is used for the signals between the LaunchPad and BOOSTXL-IOLINKM-8
boards. The LMR36503 DC-DC stepdown buck converter can be used to create the 3V3 supply rail from the 24V
rail controlled by the eFuse. However, it is possible to disable the LMR36503 and directly use the 3.3-V supply
rail from the LaunchPad with a jumper configuration.
