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 power­on 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.

Introduction
Figure 1. BOOSTXL-TPS652170 Printed Circuit Board (Top View)
This procedure requires:
1. An MSP430F5529 LaunchPad development kit, MSP-EXP430F5529LP
2. A USB A to micro B cable (included with the LaunchPad development kit)
3. A BOOSTXL-TPS652170 BoosterPack plug-in module
4. TPS652170 devices (TPS652170RSL)
5. An internet connection Specific instructions on how to program the TPS652170 using the BOOSTXL-TPS652170 with the IPG-UI
software are provided in Appendix A, while the EVM documentation related to the design of the BOOSTXL-TPS652170 hardware is provided in Appendix B.
NOTE: All re-programmed EEPROM settings must be validated during prototyping phase to ensure
desired functionality because parts cannot be returned in case of incorrect programming. Any issues should be reported to the e2e forum.

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.

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.

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.

• If all register data remains 0x00 and a red notification appears (as in Figure 10), it indicates the computer can talk to the USB2ANY (MSP430F5529 LaunchPad) but cannot communicate with the TPS652170 device. The primary cause of this issue may be that the power switch for the BOOSTXL­TPS652170 is in the OFF position, the socket does not have a sample installed, or the USB cable is not plugged into the MSP430F5529 LaunchPad or the computer. In case of either issue, the test setup of the EVM must be debugged before continuing.
