Texas Instruments TPS55288EVM-045

Overview

TPS55288EVM-045 from Texas Instruments is an evaluation module designed to demonstrate and validate the TPS55288 36-V, 16-A synchronous buck-boost converter with I²C interface. It supports input voltages from 2.7 V to 36 V and delivers programmable output voltages from 0.8 V to 20 V at up to 5 A, enabling rapid prototyping of high-efficiency power supplies in industrial, automotive, and embedded systems.

For engineers reviewing the TPS55288EVM-045 datasheet, TPS55288EVM-045 test setup, TPS55288EVM-045 GUI operation, or TPS55288EVM-045 jumper configuration, this EVM provides full hardware and software integration-including USB2ANY-based I²C control, real-time register access, and configurable feedback, enable, and frequency dithering-streamlining design validation and parameter optimization.

Technical Context

The TPS55288EVM-045 implements the TPS55288 IC in a fully assembled, tested 4-layer PCB layout with optimized thermal and EMI performance. It integrates dual 40-V, 40-A Infineon MOSFETs (IPZ40N04S5L4R8ATMA1), a 4.7-μH shielded inductor (XAL1010-472MEB), and precision current-sense resistor (CRF1206-FZ-R010ELF) for accurate ILIM programming.

Control is enabled via TI's USB2ANY adapter and dedicated GUI, supporting read/write access to all 8 registers-including output voltage (0x00–0x01), current limit (0x04), mode selection (0x05), and dithering enable (0x07)-with default switching frequency set to 400 kHz and programmable reference voltage (45 mV to 1.2 V) at the FB/INT pin.

FAQ

What is the primary function of the TPS55288EVM-045?

The TPS55288EVM-045 is an evaluation module built around the TPS55288 buck-boost converter IC. Its primary function is to provide engineers with a ready-to-use platform for evaluating the device's performance-including voltage regulation, current limiting, I²C programmability, and thermal behavior-under real operating conditions. The TPS55288EVM-045 includes all necessary passive components, MOSFETs, and interface circuitry to validate designs before committing to custom PCB development.

How do I configure the output voltage on the TPS55288EVM-045?

Output voltage on the TPS55288EVM-045 is configured via the GUI using the USB2ANY interface. The default output is 5 V, but users can adjust it between 0.8 V and 20 V by writing to registers 0x00 and 0x01. Alternatively, with JP2 set to FB_EXT and JP3 closed, external resistive feedback allows analog adjustment using Equation 1 (VOUT = VREF × (1 + RFB_UP/RFB_BT)), where VREF is programmable from 45 mV to 1.2 V. The TPS55288EVM-045 supports both methods without hardware modification.

Does the TPS55288EVM-045 support current limiting, and how is it adjusted?

Yes, the TPS55288EVM-045 supports programmable current limiting via register 0x04. The GUI provides a direct "Output Current Limit Point Setting" interface (Figure 4-6) to set the threshold. When enabled, the TPS55288EVM-045 monitors current through the 10-mΩ sense resistor (R4) and folds back output if the limit is exceeded. For loads ≥5 A, users can uncheck "Enable Current Limit" or increase the value in the GUI. This functionality is implemented directly by the TPS55288 IC and verified in the EVM's test procedure.

What hardware and software are required to operate the TPS55288EVM-045?

To operate the TPS55288EVM-045, you need the TI USB2ANY adapter (connected via J7), a PC running Windows/macOS/Linux, the USB2ANY Explorer (firmware v2.8.2.0), and the TPS55288-EVM-GUI software. The GUI auto-detects slave addresses 0x74/0x75, reads all eight registers, and provides full control over enable, voltage, current limit, mode, and dithering settings. No additional drivers or compilers are needed-the TPS55288EVM-045 operates as a plug-and-play evaluation tool upon correct jumper setup (JP1 ON, JP2/JP3 configured).

Can the TPS55288EVM-045 be used for long-term system testing or only for short evaluations?

The TPS55288EVM-045 is designed for both short-term characterization and extended system-level validation. Its 4-layer PCB features thermal vias, copper pours, and industrial-grade components-including AEC-Q200 capacitors and resistors, a 24-A composite inductor, and dual 40-A MOSFETs-enabling sustained operation at rated load. The board layout (Figures 5-2 to 5-5) and BOM (Table 5-1) reflect robust construction for reliability during burn-in, thermal stress, and functional safety verification. While not a production module, the TPS55288EVM-045 supports continuous operation when properly heatsinked and powered within spec.
