Texas Instruments BOOSTXL-TPS650861

Overview

BOOSTXL-TPS650861 from Texas Instruments is a BoosterPack™ plug-in evaluation module designed to program the one-time programmable (OTP) memory of the TPS65086100 power management IC. It features a socketed layout for rapid device swapping, supports I²C-based communication via MSP430F5529 LaunchPad™, and enables configuration of six buck converters, three LDOs, VTT regulation, and sequencing control for embedded power systems.

For engineers reviewing the BOOSTXL-TPS650861 datasheet, BOOSTXL-TPS650861 pinout, BOOSTXL-TPS650861 application, or BOOSTXL-TPS650861 equivalent, this module serves as a dedicated OTP programming interface - not a standalone power solution - requiring coordination with IPG-UI software, firmware-updated MSP430F5529 LaunchPad, and TPS65086100 devices in RSK packaging.

Technical Context

The BOOSTXL-TPS650861 operates as a hardware bridge between the MSP430F5529 microcontroller and the TPS65086100 PMIC, using GPIO-controlled CTL pins (CTL1–CTL6), SCL/SDA I²C lines, IRQB interrupt signal, and 3.3V/5V/7V supply rails. It implements voltage selection jumpers (J13–J15, J17) and a configurable VX net to support diverse input sourcing for PVIN domains including PVINLDOA2_A3, PVINSWA1, and PVINSWB1_2.

Its block-level architecture includes direct routing of BUCKx outputs, LDOA1/A2/A3, SWA1/SWB1/SWB2, VTT, and PG signals to test points and headers, enabling real-time validation of OTP-configured sequencing, rail enable timing, and fault response before deployment on target platforms like TPS650860EVM-116.

FAQ

What is the primary function of the BOOSTXL-TPS650861?

The BOOSTXL-TPS650861 is a dedicated OTP programming board for the TPS65086100 PMIC. It does not regulate power itself but provides socketed access, I²C/GPIO interfacing, and configurable jumpers to program non-volatile settings - such as rail sequencing, voltage levels, and enable timing - into the TPS65086100 device before integration into final systems.

Which development kit is required to use the BOOSTXL-TPS650861?

The BOOSTXL-TPS650861 requires the MSP430F5529 LaunchPad™ development kit (MSP-EXP430F5529LP) with updated USB2ANY_2.7.0.0_LP.txt firmware. This LaunchPad acts as the host controller, translating commands from the IPG-UI EVM GUI into physical signals sent to the TPS65086100 via the BOOSTXL-TPS650861 interface.

Can the BOOSTXL-TPS650861 be used to evaluate power performance without programming?

No - the BOOSTXL-TPS650861 is not a functional power evaluation board out-of-box. The TPS65086100 must first be programmed with valid OTP settings using IPG-UI and the BOOSTXL-TPS650861; unprogrammed or blank OTP defaults result in undervoltage lockout (SHUTDNSRC = 0x04), preventing rail activation until configuration is written and verified.

What software tools are needed to program the TPS65086100 using the BOOSTXL-TPS650861?

You need the IPG-UI EVM GUI, the TPS650861-1.0.json device file, the TPS650861-Script-1p0.js script file, the TPS65086100 OTP Generator tool (Excel-based), and the MSP430_USB_Firmware_Upgrade_Example. All are available from TI's official product folder for TPS650861 and must be synchronized to ensure correct register mapping and OTP bank handling.

Does the BOOSTXL-TPS650861 support multiple TPS650861 variants?

The BOOSTXL-TPS650861 is explicitly validated for the TPS65086100RSK variant per TI's SWCU190 User's Guide. While other TPS650861 family members share similar architecture, differences in OTP structure, register maps, or pin functions mean compatibility with non-TPS65086100 devices is not guaranteed and requires verification against their respective programming guides.
