FIGURE 2-4: Evaluation Board Top View - Data Test Points.
J18 Current Limit
Stand-Alone mode
Placing one jumper on this header selects the current limit and
sets the UCS1003-1 in Stand-Alone mode. In this case, no jumper
must be populated on J16 header.
J17 SMBus Address
PWR_EN active low
Placing one jumper on this header selects the SMBus address
and sets the PWR_EN control to be active low. In this case, no
jumper must be populated on J19 header.
J19 SMBus Address
PWR_EN active high
Placing one jumper on this header selects the SMBus address
and sets the PWR_EN control to be active high. In this case, no
jumper must be populated on J17 header.

Description
Note 1:
The following headers must be populated with one jumper for the UCS1003-1 Evaluation Board to be
functional:
• J4, J5, J8
• J16 or J18
• J17 or J19
• If the UCS1003-1 is configured in SMBus mode (as selected by using J16 instead of J18, two
jumpers must be populated on J7; J6 must be left unpopulated. If the UCS1003-1 is configured in
Stand-Alone mode, the jumpers on J7 must be left off.)
