Texas Instruments TPS552882EVM-2MHZ

Overview

TPS552882EVM-2MHZ from Texas Instruments is an evaluation module designed to demonstrate and validate the TPS552882 36-V, 16-A synchronous buck-boost converter IC with integrated high-side and low-side MOSFETs, configured for a fixed 2-MHz switching frequency, supporting 2.7–36-V input and 0.8–20-V output in power supply design labs and embedded power system development.

For engineers reviewing the TPS552882EVM-2MHZ datasheet, TPS552882EVM-2MHZ pinout, TPS552882EVM-2MHZ application, or TPS552882EVM-2MHZ equivalent, this EVM enables rapid characterization of transient response, efficiency mapping, thermal performance, and loop stability under real-world load and input conditions - especially for automotive infotainment, industrial HMIs, and wide-input DC-DC conversion applications.

Technical Context

The TPS552882EVM-2MHZ implements the TPS552882RPM VQFN-HR26 buck-boost controller IC with dual 16-A internal MOSFETs, operating at a fixed 2-MHz switching frequency to minimize external passive size while maintaining >90% peak efficiency across 5-A/5-V, 3-A/9-V, and 2-A/15-V output configurations.

It features configurable enable (JP1), frequency dithering control (JP2), and four dedicated I/O connectors (J1–J4) for isolated input/output voltage and return paths, enabling precise bench-level measurement of regulation accuracy, load step response, and input ripple rejection without signal coupling.

FAQ

What is the primary function of the TPS552882EVM-2MHZ?

The TPS552882EVM-2MHZ is an evaluation module built around the TPS552882RPM buck-boost converter IC. Its primary function is to provide a fully assembled, tested, and documented platform for engineers to evaluate the electrical performance, thermal behavior, and system integration of the TPS552882 device - including efficiency, load regulation, transient response, and stability - under real-world input/output conditions without custom PCB development. The TPS552882EVM-2MHZ itself does not perform power conversion independently; it hosts and exposes the capabilities of the TPS552882 IC.

Does the TPS552882EVM-2MHZ support adjustable switching frequency?

No, the TPS552882EVM-2MHZ is configured for a fixed 2-MHz switching frequency as indicated by its part number and confirmed in Table 1-1 of the user's guide. The JP2 jumper controls frequency dithering (ON/OFF), not frequency selection. The underlying TPS552882RPM IC supports programmable frequency via external resistor, but this EVM uses a fixed resistor network to set 2 MHz - no on-board means exist to change that value without hardware modification. Therefore, the TPS552882EVM-2MHZ delivers consistent 2-MHz operation out-of-box.

Can the TPS552882EVM-2MHZ be used to evaluate different output voltages?

Yes, the TPS552882EVM-2MHZ supports output voltage adjustment from 0.8 V to 20 V by modifying the feedback resistor divider (R2, R7, R9, R10, R11). The default configuration delivers a specific output, but the board includes solder pads and documentation (schematic Figure 4-1) showing how to reconfigure resistors to target alternate regulated outputs. This flexibility allows engineers to validate the TPS552882 IC's performance across multiple rail requirements using the same TPS552882EVM-2MHZ hardware.

What are the key connectors and their roles on the TPS552882EVM-2MHZ?

The TPS552882EVM-2MHZ uses four primary screw-terminal connectors: J1 (input voltage positive), J2 (input return), J3 (output voltage), and J4 (output return). These provide galvanically isolated, low-inductance access to input and output power paths - essential for accurate bench measurements without ground-loop interference. All connectors are rated for secure mechanical attachment and compatible with standard lab power supplies and electronic loads, ensuring repeatable testing of the TPS552882 IC's regulation and transient behavior.

Is thermal performance data available for the TPS552882EVM-2MHZ?

Yes, thermal performance is characterized in the user's guide test procedures and supported by the board's copper pour layout and component placement. While absolute temperature rise values are not tabulated in isolation, Section 3 confirms stable regulation up to 3 A at 12-V input/5-V output with ambient at 25°C, and the inclusion of a 18-A composite inductor (XAL6030-102MEB) and polymer/hybrid capacitors indicates thermal-aware design. Full thermal imaging or junction temperature data requires external measurement using TP1–TP8 test points, as the TPS552882EVM-2MHZ provides physical access for IR camera or thermocouple placement per Figure 4-2 through Figure 4-5.
