1 Introduction

The TPS65941x-Q1 PMIC family is extremely flexible and scalable, providing configurability at the device and system level. At the device level, a single PMIC can provide up to five separate step down converters (BUCK regulators) and four LDOs. Four of these BUCK regulators can be used in multi-phase mode to provide a single 14 A source. At the system level, several PMICs can be configured to work in a master-slave topology with one master and up to five slave PMICs. The TPS65941x-Q1 EVM is both an evaluation and development tool. With the EVM both device level and system level configurability are available through an easy to use graphical user interface (GUI) tool.

Table 1-1 shows the available master and slave EVMs, the silicon associated with those EVMs, the initial non-volatile memory (NVM) configuration, and the hardware components associated with the configurations. Any EVM can be configured as a master or slave device because of the configurable nature of both the part and the EVM. Master and slave configurations are provided to facilitate getting started and to accelerate development.
