TPS60100 and TPS60110 EVM
1.2 Schematic of the EVM
The schematics of the two EVMs for TPS60100 and TPS60110 are the same.
The differences between the boards are the IC itself, the values for the external
components (see Table 1–1), and the use of the connector 3V8. The connector
3V8 can be used on the EVM for TPS60100 to adjust the output voltage to 3.8
V. This mode is not implemented on the TPS60110. As long as you do not want
to synchronize the TPS60110, connect this pin with a jumper to GND. When
the TPS60100 or the TPS60110 is synchronized, the second pin of the con-
nector 3V8 is used to apply the external clock signal.

are the two ceramic capacitors for reducing the spikes.
If spikes are not critical in your application, it is possible to remove these two
capacitors.
For the input and output of the voltage, there are two six-pin connectors on the
board. Each has the first three pins for the supply (IN or OUT) and the last three
pins for the ground (GND) signal.
The five three-pin connectors can be used to connect the five logic pins of the
device. These pins are used to adjust the modes of the devices
