Texas Instruments TPS65276VTEVM

Overview

TPS65276VTEVM from Texas Instruments is an evaluation module for the TPS65276V dual-output synchronous step-down PMIC, supporting 4.5–18 V input and delivering up to 6.5 A on Buck1 and 3.5 A on Buck2 with I²C-controlled VID voltage programming (0.68–1.95 V), externally adjustable switching frequency (200 kHz–1.6 MHz), and current-sharing capability. It enables rapid validation of power architecture in industrial and embedded computing applications.

For engineers reviewing the TPS65276VTEVM datasheet, TPS65276VTEVM hardware setup, TPS65276VTEVM software GUI operation, or TPS65276VTEVM BOM integration, this EVM provides full access to I²C register control, jumper-configurable enable/mode/address settings, SYNC input, test points for LX and output monitoring, and USB-to-GPIO interface support for real-time voltage and mode adjustment.

Technical Context

The TPS65276VTEVM implements the full feature set of the TPS65276V PMIC, including dual independent buck regulators with soft-start, external compensation, and selectable operation modes (forced PWM, auto PSM-PWM, or current-share). It supports I²C address configuration (0x60H–0x62H) via JP7 and mode selection (JP8) for system-level power optimization.

Hardware design includes dedicated headers (J1 for 4.5–18 V input; J18/J31 for VOUT1/VOUT2 outputs), test points for LX1/LX2 switching nodes, and a 10-pin I²C interface (JP15) compatible with TI's USB-TO-GPIO adapter. The board uses 3.3 µH power inductors (L1/L2), 22 µF ceramic output capacitors, and configurable enable jumpers (JP1/JP2) with 100-kΩ pull-up resistors.

FAQ

What is the primary function of the TPS65276VTEVM?

The TPS65276VTEVM is an evaluation module for the TPS65276V dual-output synchronous buck converter PMIC. Its primary function is to provide engineers with a ready-to-use hardware platform to validate voltage regulation performance, I²C-based VID programming, current sharing behavior, and mode switching (PWM/PSM) under real-world load and thermal conditions before final system integration. The TPS65276VTEVM includes all necessary components, test points, and interface hardware to exercise every documented feature of the TPS65276V IC.

Does the TPS65276VTEVM support both I²C and resistor-based voltage programming?

Yes, the TPS65276VTEVM supports both methods. I²C-controlled VID programming is enabled by default when JP9 is configured for 3.3 V I²C power and JP7 sets the correct I²C address (e.g., 0x60H with JP7 grounded). Resistor-based programming remains fully accessible via external feedback dividers on the U1 TPS65276V IC - the board includes unpopulated pads and routing to support manual resistor configuration without modifying the EVM layout. This dual-path flexibility allows verification of both digital and analog control schemes using the same TPS65276VTEVM hardware.

How is current sharing implemented on the TPS65276VTEVM?

Current sharing on the TPS65276VTEVM is activated by configuring JP8 to connect to Vcc (6.25 V), placing the TPS65276V IC into current-share mode. In this mode, the device monitors output current via internal sensing and communicates with peer devices on the same I²C bus to balance load distribution across parallel converters. The TPS65276VTEVM provides all required signal routing and termination for multi-device synchronization, though full current sharing requires at least two TPS65276VTEVM units or one TPS65276VTEVM paired with another TPS65276V-based board operating on the same I²C bus with matching address and mode settings.

What software tools are required to operate the TPS65276VTEVM?

The official TPS65276V EVM Software - provided by Texas Instruments - is required to operate the TPS65276VTEVM via its USB-TO-GPIO interface. This Windows-based GUI application enables real-time read/write access to all five internal registers (two for VID, two for configuration, one for status), supports "write-on-change" or manual register update, and displays live voltage and mode settings. The TPS65276VTEVM ships with a compatible USB-TO-GPIO adapter box; no third-party drivers or custom firmware are needed - the TPS65276V EVM Software handles automatic firmware updates and communication handshaking directly with the TPS65276VTEVM hardware.

Can the TPS65276VTEVM be used for long-term reliability testing?

No - the TPS65276VTEVM is explicitly designated for engineering development, demonstration, and feasibility evaluation only, not for production or long-term reliability testing. As stated in TI's EVM terms, it is not a finished end-product and lacks environmental certifications (e.g., UL, CE, FCC Class B compliance is not claimed). Its PCB layout, component selection, and thermal design prioritize debug accessibility and feature coverage over sustained high-load operation. For reliability validation, users must migrate to a production-grade design incorporating the TPS65276V IC with appropriate derating, safety margins, and certified compliance testing - the TPS65276VTEVM serves solely as a functional proof-of-concept platform.
