The MAX8569 EV kit is a fully assembled and tested
surface-mount circuit board. Follow the steps below to
set up and verify both packages of the MAX8569B and
board operation. Place a “1” in the “_” (e.g., JU_
becomes JU1) when evaluating the 6-pin SOT23 pack-
age (U1, Figure 1). Place a “2” in the “_” (e.g., JU_
becomes JU2) when evaluating the 6-pin TDFN (3mm x
3mm) package (U2, Figure 1).
1) Preset the power supply (PS1) to 2.5V. Turn off the
2) Preset the electronic load (EL1) to 200mA. Turn off
3) Verify on the MAX8569 EV kit that there are shunts
4) Connect the positive lead of PS1 to BATT_ and the
5) Connect the positive lead of DMM1 to VOUT_ and
