TPS659037 EVM User’s Guide
This user’s guide describes the characteristics, operation, and use of the TPS659037EVM. An EVM
description, GUI description, interface requirements, and complete schematic are included.
1 Introduction
The TPS650937 device is a power-management integrated circuit (PMIC) for industrial and consumer
applications. The device provides seven configurable step-down converters, with up to 9 A of output
current for memory, processor core, input/output (I/O), or preregulation of LDOs. The TPS659037 device
contains 7 LDO regulators for external use. For more details, see the device datasheet, TPS659037
Power Management Unit (PMU) for Processor,SLIS165.
1.1 EVM Overview
The features of this EVM are as follows:
• Allows monitoring of all LDO and SMPS output voltages.
• Allows loading of all SMPS outputs.
• Allows access to the GPIOs and other logic signals to test functionality.
• Optimized layout for stable operation of all SMPS.
• Onboard MSP430 to enable communication with the PMIC.
• Graphical User Interface (GUI) on Windows®to allow access to the registers of the PMIC through
USB-I2C.

LEDs— Display status of POWERGOOD, RESET_OUT, LDORTC and power supply of MSP430
USB— Connection to PC to enable communication through the GUI
MSP430— Microcontroller used to convert USB data to I2C format
SMPSxx— Monitor point for SMPS outputs
J46— Monitor point for LDO outputs
J31— Jumper used to select VIO voltage. J31 requires a jumper installed (only one), and by default is in
position 10, 1V8.
J27— Jumper that provides access to the GPIOs
J20— VSYS power supply input. J20 is the same connector as SMPS123, and must not be confused to
prevent applying VSYS to SMSP123-output.

1.3 Power-Supply Requirements and Connections
Only one power supply is needed to power the VSYS domain of the PMIC. Apply 3.135 VDC to 5.25 VDC
to the J20 connector of the TPS659037EVM to supply power to the PMIC device. Four-wire sensing of the
input power supply is recommended and can be achieved through the middle two terminals of J20.
Power for the MSP430 and the two fixed voltage LDOs (3.3-V and 1.8-V outputs) is supplied through the
USB connection, as shown in Figure 2.
