TPS65084x Evaluation Module
1 Introduction
The TPS65084x is a highly integrated power management solution for the Intel Braswell processors.
Features of the TPS65084x include:
• Three Variable-Output Voltage Step-Down Controllers
– Wide V
IN
range from 5.4 V to 21 V
– Up to 7-A output current for BUCK1 (VCC) and BUCK6 (VDDQ), and 11-A for BUCK2 (VGG) using
external FETs
– I
2
C DVS Control (0.5 V to 1.45 V in 10-mV steps) for BUCK1 and BUCK2
– Pin-selectable output voltages (1.1 V, 1.2 V, or 1.35 V) for BUCK6 (VDDQ)
• Three variable-output voltage synchronous step-down converters
– V
IN
range from 4.5 V to 5.5 V
– Up to 3.5 A of output current for BUCK3 (VNN) with I
2
C DVS control (0.65 V to 1.45 V in 25-mV
steps)
– Up to 3 A of output current for BUCK4 (V1P05A) and up to 1.5 A of output current for BUCK5
(V1P8A)
• Three LDO regulators with I
2
C-adjustable-output voltage
– LDOA1: from 1.35 V to 3.3 V for up to 200 mA of output current
– LDOA2: from 1.05 V, 1.1 V, 1.15 V, and 1.2 V for up to 500 mA of output current

– R
DSON
< 96 m
Ω
at input voltage of 1.8 V
• I
2
C interface (Device Address 0x5E) supports standard mode (100 kHz), fast mode (400 kHz), and fast
mode plus (1 MHz)
• 64-Pin, single-row, 0.4-mm pitch QFN package
2 Requirements
2.1 Software
The EVM will power-up and operate without use of software. A GUI is supplied to provide a simple way to
communicate to the device via I
2
C. The GUI can be downloaded from:
http://www.ti.com/tool/IPG-UI
Additional installers are needed to update the GUI to contain the register map for this device. They can be
downloaded from:
https://ti.com/licreg/docs/swlicexportcontrol.tsp?form_id=184041&prod_no=TPS65084X_94X&ref_url=hval
_ipg
The EVM has a built-in USB2ANY module utilizing an MSP430. The GUI uses this to communicate with
the device.
2.2 Host Computer
A computer with an available USB port is required to make use of the EVM software. The EVM software
runs on the computer and communicates with the EVM via a USB-A to micro-B cable.
