5.2 Configuring the Bucks

There are several settings that can be programmed for the Buck converters. These include the output voltages, under voltage (UV) monitoring, and bandwidth among others.

  • Figure 5-2 shows the settings to be changed when using the configuration tab of the TPS65214-GUI.
  • Table 5-2, Table 5-11, and Table 5-4 show the register fields to be written when referring to the register map.
