1 Introduction

The configuration process described in this document writes to the NVM space and is intended to be used in a production line or prototype board. This mechanism is not intended to be used in final applications because the process impacts the regulator outputs and the function of digital pins. The TPS6521905 is an orderable part number, part of the TPS65219 family, created specifically to support custom NVM configuration. Table 1-1 shows the user-programmable variants and the supported package size, temperature, and switching mode. Figure 1-1 describes the supply options for pre-configured and custom NVMs based on volume. Design resources are available not only for pre-configured and high volume NVMs, but also for low volume custom NVMs. These resources can include application notes, user's guides, technical reference manuals, and NVM configuration files ready to be loaded into the PMIC NVM. Visit the TPS6521905 product page on ti.com or use our PMIC E2E forum to ask about available resources.

Note: To support NVM programming, TI offers two socketed EVMs, one for each package size. TPS65219EVM-SKT is the orderable part number for the 5x5 socketed EVM and TPS65219EVM-RSM is the orderable part number for the 4x4 socketed EVM.
