5.2.1 Initial EVM Jumper and Switch Settings

Figure 5-2 is the basic test setup recommended for evaluating the TPS40100EVM-001. The EVM is shipped with the following in the default position:

  • The enable switch (S1) is open across pins 2 and 3. This is the enable position.
  • The tracking enable jumper (J8) has shunt positioned across pins 1 and 2, disabling the tracking feature.
  • The tracking engage switch (S2) is open across pins 2 and 3. This enables the tracking ramp to charge.
  • Remote sense jumpers (J6 and J7) have shunts positioned across pins 2 and 3, enabling local connector sensing.
  • Margin shunts positioned in the margin disable position.
