Introduction

1.4

Setup of the EVMs

It is important to establish all connections to the EVM before the power supply
connected to the EVM is turned on.

1) Connect a power supply (0.9 V to V

, depending on the output voltage of

the EVM) to the INPUT header.

2) Connect a voltmeter to the OUTPUT header.

3) Verify that the jumper, J1, is set to EN.

4) Verify that the jumper, J2, is set to TBD.

5) Turn on the power supply and verify the output voltage.
