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.

2 Getting Started
The USB must be connected to a host PC in order to evaluate the EVM, because the default configuration does
not enable the regulators. A type-A to type-C cable is provided with the EVM to connect to the host computer.
The EVM will enumerate as two COM ports and one additional port for the devices firmware updates. The
Scalable PMIC GUI will provide an interface to configure the regulators for evaluation. Please refer to the
SLVUBT8 for more information.
The USB can also be used to provide power to the PMIC but it is not recommended when evaluating the
regulators. The remainder of this document describes the different connectors and jumpers available on the
EVMs.
Figure 2-1 and Figure 2-2 shows the TPS6594EVM and the TPS6593EVM respectively.
