TPS65916 EVM User’s Guide
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.
1.2 EVM with Components Identified
Figure 1. EVM
LEDs — Display status of POWERGOOD, RESET_IN, POWER_HOLD, LDOVRTC_OUT, RESET_OUT,
INT, and power supply of MSP430
USB — Connection to PC to enable communication through the GUI
MSP430 — Microcontroller used to convert USB data to I
2
C format
SMPSxx — Monitor point for SMPS outputs
LDO Outputs — Monitor point for LDO outputs
VIO SelectorX — Jumper used to select VIO voltage. P12 requires a jumper installed, and by default pins
11 and 12 are shorted to select external 1.8 V as VIO. Only one jumper should be installed
between P12 and P15.
GPIOs — Jumper that provides access to the GPIOs
VSYS — VSYS power supply input. P16 is the same connector as SMPS12_OUT and must not be
confused to prevent applying VSYS to SMPS-output.
