Quick Start Guide
Figure 1 shows a photograph of the evaluation board. Please refer to this figure while
configuring the board for evaluation.
STEP 1: Set the “ENABLE” jumper to the Disable Position.
STEP 2: Select the desired VOUT voltage setting by placing the jumper J2 on the

correct jumper pin. Figure below shows the VOUT jumper options and their
nominal voltages. Note that depending on the tolerance of the resistors
populated on the board, each output voltage setting may have a larger
tolerance than just the VFB pin as specified in the datasheet. Please see
Figure 3 and the Bill of Materials section. Multiple jumpers can be populated to
get other output voltages not listed below. With the resistors shown below, if all
4 jumper positions are populated, the output voltage will be approximately
3.7V. Note that for any VOUT higher than 3.3V, the output capacitors need to
be changed to 2 x 22uF/0805.
