5.3 Configuring LDOs

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

  • Figure 5-3 shows the settings to be changed when using the configuration tab of the TPS65214-GUI.

  • Table 5-5 and Table 5-6 show the register fields to be written when referring to the register map.
