Texas Instruments TPS628304ADRLEVM

Overview

TPS628304ADRLEVM from Texas Instruments is an evaluation module designed to validate the TPS628304ADRLR 4-A synchronous buck converter in SOT583 package, operating from 2.25 V to 5.5 V input and delivering a regulated 1.8 V output. It supports hardware setup via jumper-configurable EN and MODE pins, includes test points for input/output voltage sensing, and enables loop response measurement.

For engineers reviewing the TPS628304ADRLEVM datasheet, TPS628304ADRLEVM hardware setup, TPS628304ADRLEVM test results, or TPS628304ADRLEVM schematic and BOM, this EVM provides validated reference design data, dual-voltage sense capability, and direct access to critical control signals (EN, MODE, PG) for rapid functional verification of high-efficiency DC-DC conversion in space-constrained applications.

Technical Context

The TPS628304ADRLEVM implements the DCS-Control topology with integrated noise filtering capacitors, enabling fast transient response and excellent EMI performance. It uses the TPS628304ADRLR IC in 1.6 mm × 2.1 mm SOT583 package, supporting fixed-frequency PWM or power-save mode via MODE pin configuration.

This EVM features dedicated input/output voltage sense connectors (J1 S+/S–, J2 S+/S–), PG signal header (J3), and configurable jumpers (JP1 for EN, JP2 for MODE). It supports optional external input/output capacitors (C2/C3/C9) and loop response measurement via R3 trace cut and 50-Ω injection point.

FAQ

What is the primary function of the TPS628304ADRLEVM?

The TPS628304ADRLEVM is an evaluation module built around the TPS628304ADRLR 4-A buck converter. Its primary function is to provide a ready-to-use platform for evaluating the electrical performance, thermal behavior, and control interface operation of the IC under real-world conditions-including input/output voltage regulation, transient response, and EMI characteristics-without requiring custom PCB development.

Does the TPS628304ADRLEVM support adjustable output voltage?

No, the TPS628304ADRLEVM is configured for a fixed 1.8 V output using the internal feedback resistor network of the TPS628304ADRLR IC. While the underlying IC supports external resistor-based adjustment, this EVM does not include provisions for modifying the FB divider; it is intended for validation of the standard 1.8 V configuration as specified in the device datasheet.

How is the enable and mode functionality implemented on the TPS628304ADRLEVM?

The TPS628304ADRLEVM implements EN and MODE control via two 3-pin headers: JP1 (ON/EN/OFF) and JP2 (VIN/MODE/GND). Placing the jumper across ON–EN enables the IC; across OFF–EN disables it. JP2 configures operation mode: VIN–MODE forces fixed-frequency PWM, while MODE–GND enables power-save mode - both functions are directly tied to the corresponding pins of the TPS628304ADRLR IC on the board.

Can the TPS628304ADRLEVM be used to measure loop stability?

Yes, the TPS628304ADRLEVM supports loop response measurement. As described in Section 2.3.2 of the user's guide, users can cut the trace parallel to R3 and install a 50-Ω resistor in its place to inject an AC signal for Bode plot analysis using a network analyzer - enabling direct validation of compensation and phase margin for the TPS628304ADRLR control loop.

Is the TPS628304ADRLEVM FCC-certified for emissions testing?

No, the TPS628304ADRLEVM is not FCC-certified. Per TI's Standard Terms for Evaluation Modules, it is intended solely for R&D use in shielded lab environments and is not authorized for resale or integration into finished products. While it incorporates design practices aligned with Class A digital device limits per FCC Part 15, formal certification requires full-system validation under applicable regulatory frameworks.
