Texas Instruments BOOSTXL-TPS652170

Overview

BOOSTXL-TPS652170 from Texas Instruments is a BoosterPack evaluation module (EVM) designed to program and verify EEPROM-configurable parameters of the TPS652170 power management IC (PMIC), including output voltages (DCDC1–DCDC3, LDO1–LDO2, LS1/LDO3, LS2/LDO4), power-up/power-down sequencing order (SEQ1–SEQ6), slew rate control, and supervisor thresholds. It enables rapid prototyping for processor and FPGA power delivery validation.

For engineers reviewing the BOOSTXL-TPS652170 datasheet, BOOSTXL-TPS652170 pinout, BOOSTXL-TPS652170 application, or BOOSTXL-TPS652170 equivalent, this EVM supports I²C-based register read/write, EEPROM reprogramming via IPG-UI software, real-time voltage/sequence measurement at dedicated test points (TP5–TP17), and integration with MSP430F5529 LaunchPad for USB-hosted configuration.

Technical Context

The BOOSTXL-TPS652170 provides physical socket-based access to the TPS652170RSL PMIC, enabling non-destructive programming and verification before solder-down on target systems. It routes all critical I²C (SCL/SDA), control (nRESET, PWR_EN), and power (SYS, USB, AC) signals between the PMIC and MSP430F5529 LaunchPad via dual 20-pin headers (J1–J4).

It includes configurable jumpers (J5/J6) to select input sources for load switches LS1/LS2, test points for all regulated outputs (VDCDC1–VDCDC3, VLDO2, LS1_OUT, LS2_OUT), and hardware-level power enable logic requiring ≥7 V on PWR_EN for EEPROM write operations.

FAQ

What is the BOOSTXL-TPS652170 used for?

The BOOSTXL-TPS652170 is a hardware evaluation module that enables engineers to program, verify, and validate EEPROM-stored configuration parameters of the TPS652170 PMIC - including output voltages, sequencing order, slew rates, and supervisor thresholds - before deploying the device in final designs. It supports full register-level access via IPG-UI software and real-time measurement at dedicated test points.

Which development board is required to operate the BOOSTXL-TPS652170?

The BOOSTXL-TPS652170 requires the MSP430F5529 LaunchPad (MSP-EXP430F5529LP) as its host interface. The LaunchPad provides I²C communication, USB-to-serial bridging, and 5 V power via micro-USB. Firmware must be updated to USB2ANY_2.7.0.0_LP.txt prior to connection, and the BOOSTXL-TPS652170 plugs directly onto the LaunchPad's BoosterPack headers.

Can the BOOSTXL-TPS652170 reprogram the TPS652170 EEPROM without external power?

Yes - the BOOSTXL-TPS652170 operates entirely from the 5 V supplied by the MSP430F5529 LaunchPad's USB port. However, successful EEPROM reprogramming requires ≥7 V on the PWR_EN pin of the TPS652170, which is achieved internally via the BOOST_EN signal path driving the TPS61093 boost converter to generate 8 V. No external power supply is needed.

How are load switches LS1 and LS2 configured on the BOOSTXL-TPS652170?

LS1 (LDO3) and LS2 (LDO4) are configured via jumper headers J5 and J6. By default, J5 shunts pins 1–2 (LS1_IN to DCDC1) and J6 shunts pins 1–2 (LS2_IN to SYS), enabling LS1 as an LDO powered by DCDC1 and LS2 as an LDO powered by SYS. Reprogramming these as load switches requires moving jumpers to alternate positions per Table 3 in the user's guide.

Does the BOOSTXL-TPS652170 support measuring power sequencing timing?

Yes - the BOOSTXL-TPS652170 provides direct access to all regulated outputs (VDCDC1–VDCDC3, VLDO2, LS1_OUT, LS2_OUT) via dedicated test points (TP11, TP14, TP15, TP8, TP10, TP6, TP7). Engineers can use oscilloscopes or logic analyzers connected to these points to capture and validate power-up/down timing sequences defined in SEQ1–SEQ6 registers of the TPS652170.
