BOOSTXL-TPS652170 EVM User's Guide

The BOOSTXL-TPS652170 is a BoosterPack evaluation module (EVM) for programming samples of the

TPS652170 power management IC (PMIC) with user-defined values for output voltage, sequence timing,

and other critical parameters. Modifying these parameters using the BOOSTXL-TPS652170 allows for

rapid prototyping and quick time to market when using the TPS652170 PMIC to provide power to a variety

of processors and FPGAs.

This document provides a description of how to setup the EVM and re-program the EEPROM memory of

the TPS652170 devices using the BOOSTXL-TPS652170 BoosterPack, an MSP430F5529 LaunchPad,

and the IPG-UI software. The steps in this document describe the procedure for programming samples of

the TPS652170 installed in the socket of the BOOSTXL-TPS652170 printed circuit board (PCB).

1 Introduction

The BOOSTXL-TPS652170 allows designers to program samples of the TPS652170 and verify the values

in the EEPROM match the power-up and power-down sequence requirements of the targeted processor

that will be powered by the PMIC in the final application. The BOOSTXL-TPS652170 BoosterPack EVM is

simple to test, requiring only an MSP430F5529 LaunchPad and USB A-to-micro B cable. With no load or a

light load on the BoosterPack EVM, the power provided by the LaunchPad is sufficient to power the

TPS652170 device, re-program the EEPROM, and perform all of the measurements described in this

document. The 5 V provided by the VBUS wire of the USB cable is the only power input to the

LaunchPad.

The TPS652170 device consists of three step-down converters (DCDC1, DCDC2, DCDC3), one WLED

boost converter (DCDC4), two general-purpose LDO regulators (LDO1, LDO2), and two load switches that

can be purposed as LDO regulators (LS1/LDO3, LS2/LDO4). The output voltage of all the DC/DC

converters and the LDO regulators is programmable. Configuring the load switches as additional LDO

regulators is programmable. The sequence order of all DC/DC converters, the LDOs, and the load

switches can also be programmed and assigned to integer values relative to each other. The sequence

timing and supervisor thresholds are global parameters that can be programmed. The integrated battery

charger of the TPS652170 can also be programmed but the BAT, BAT_SENSE, and TS pins are not

routed out to test points on the BOOSTXL-TPS65218.

Modifying some or all of these register map values and re-programming the EEPROM of the TPS652170

device with the IPG-UI software creates new reset values for the PMIC, which allows the PMIC to power-

on and power-off with the required timing for a variety of processors or FPGAs.

Figure 1 shows the top-side of the BOOSTXL-TPS652170 PCB, on which a socket is placed to install

TPS652170 samples and re-program the samples. The samples can then be removed from the socket

and soldered down on a TPS65217xEVM or prototype PCB to evaluate the power delivery capabilities of

the TPS652170 newly programmed for a specific processor or FPGA. If the output voltages or sequencing

are not ideal for the processor or FPGA on the first attempt, the process can be repeated until the ideal

programming of the TPS652170 device is determined.

1.2 Required Hardware

1.2.1 MSP430F5529 LaunchPad

The MSP430F5529 LaunchPad will serve as a communication interface between the IPG-UI software and

the TPS652170 device. The firmware on the MSP430F5529 needs to be updated before it can

communicate with the TPS652170. Figure 2 shows the BOOSTXL-TP652170 connected on top of the

MSP430F5529 LaunchPad with a micro-USB cable inserted in the LaunchPad.

Figure 2. BOOSTXL-TPS652170 and MSP430F5529 LaunchPad Connected

NOTE: Do not plug the BOOSTXL-TPS652170 BoosterPack into the MSP430F5529 LaunchPad

before the firmware is updated, as described in Section 2.5.

2 Getting Started

Figure 3 shows the high-level block diagram of the BOOSTXL-TPS652170 as it is wired to the

MSP430F5529 LaunchPad through the two 20-pin headers connecting the two PCBs. It also shows the

LaunchPad connected to a computer through a USB cable, which is required for programming the

TPS652170 device.

2.1 Connecting Headers

This section describes the headers on the BOOSTXL-TPS652170 used to connect the BoosterPack EVM

to the MSP430F5529 LaunchPad. There are two sets of headers numbered J1-J4, each set having two

rows of 10 pins, for a total of 40 pins. The outside headers, closest to the board edge, are J1 (left) and J2

(right). The inside headers, closest to the socket on BOOSTXL-TPS652170 and closest to the

MSP430F5529 device on the LaunchPad, are J3 (left) and J4 (right). When connected correctly, all 40

pins of the headers make a physical connection from board to board and the headers numbers line up (in

other words, J1 connects to J1, J2 connects to J2, and so forth.). However, all 40 pins do not make an

electrical connection from the LaunchPad to the BOOSTXL-TPS652170 design.

Table 1 lists all of the electrical connections made when the headers of the BOOSTXL-TPS652170 and

MSP430F5529 LaunchPad are connected correctly.

(1) The net named 3V3LP is re-named 3V3SW after the current-limiting switch controlled by S1 and provides a pull-up reference

voltage for SCL, SDA, INT, nWAKEUP, and LED D7 driven by the PGOOD pin of the TPS652170 device.

(2) The BOOST_EN signal is for the TPS61093 and does not connect to the TPS652170. Enabling the boost provides 8 V to the

PWR_EN pin, which is sufficiently high to allow re-programming of the EEPROM.

(3) The net named USBLP is re-named USBSW after the current-limiting switch controlled by S1 and provides power (5 V) to the

USB pin of the TPS652170 device directly from VBUS of the USB cable. USBSW is the only supply available and generates

SYS, which provides power to all VIN_DCDCx pins, VINLDO, and LSx_IN.
