TPS6594x-Q1 Evaluation Module

Introduction
The TPS65941x-Q1 power management integrated circuit (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 14A 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 evaluation module (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.
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. Because of the configurable nature of both the part and the EVM, any EVM can be
configured as a master or slave device. Master and slave configurations are provided to facilitate getting
started and to accelerate development.

Getting Started
Only a power supply and the EVM are required to evaluate and test the TPS6594x-Q1 default
configuration under load conditions. This section contains the master and slave configurations and
how to run these two default configurations.
2.1
Getting Started: Single EVM
1. Connect Power to the EVM.
2. Connect the EVM to the Host PC through the USB. In the event that the power is provided by the USB
cable, apply the appropriate jumper connection to connect VBUS and VSYS see
3. Launch the GUI and evaluate.
Terminal J6, labeled VSYS_IN in
, can accept wire gauges up to 14 AWG. The voltage supplied
must be within the input range of the device, 2.7 V to 5.5 V. The power supply providing the input to
VSYS_IN is required to supply 120% of the output power. Once power has been supplied to VSYS_IN, the
pullup on nPWRON/ENABLE pin will enable the device and the power output rails will activate. The
default ON Request for the master device is the ENABLE pin which is a level sensitive input. Please refer
to
for more details.
