Texas Instruments TPS62480EVM-671

Overview

TPS62480EVM-671 from Texas Instruments is an evaluation module designed to accelerate development and validation of the TPS62480 dual-phase 6-A synchronous buck converter. It supports input voltages from 2.4 V to 5.5 V, delivers regulated 1.8-V or 2.5-V output at up to 6 A, and enables rapid testing of power stage efficiency, thermal performance, loop stability, and transient response in high-density DC/DC applications.

For engineers reviewing the TPS62480EVM-671 datasheet, TPS62480EVM-671 setup, TPS62480EVM-671 test results, or TPS62480EVM-671 board layout, this EVM provides full access to all control pins (EN, MODE, VSEL, SS/TR, PG, TG), configurable voltage tracking, jumper-selectable operating modes (PWM/PSM), and dual-input/output terminal options for low- and high-current test configurations.

Technical Context

The TPS62480EVM-671 implements the TPS62480 IC in a production-ready 2-layer PCB layout optimized for thermal management and signal integrity. It integrates two 470-nH shielded inductors (L1/L2), 100-µF bulk output capacitance (C8), and multiple 22-µF ceramic capacitors (C1–C6) to support stable 6-A operation under PSM or forced PWM mode across 2.4–5.5-V input range.

All critical converter interfaces are exposed via headers (J1–J7) and jumpers (JP1–JP5), enabling real-time configuration of enable state, output voltage (1.8 V / 2.5 V), operating mode, soft-start timing, power-good logic level, and tracking-voltage scaling - directly mirroring system-level integration requirements for FPGA, ASIC, and SoC core rail designs.

FAQ

What is the primary function of the TPS62480EVM-671?

The TPS62480EVM-671 is an evaluation module built around the TPS62480 dual-phase 6-A buck converter. Its purpose is to provide engineers with a fully assembled, tested, and documented platform to validate voltage regulation, thermal behavior, loop stability, and transient response before integrating the TPS62480 into end equipment. The TPS62480EVM-671 includes all necessary passive components, configurable jumpers, and test points to replicate real-world application conditions without requiring custom PCB development.

Can the TPS62480EVM-671 be used to evaluate both 1.8-V and 2.5-V output configurations?

Yes, the TPS62480EVM-671 supports both 1.8-V and 2.5-V output voltages via the JP2 jumper. Placing the jumper across LOW and VSEL configures the TPS62480 for 1.8-V operation, while placing it across HIGH and VSEL selects 2.5-V output. This dual-voltage capability allows direct evaluation of the TPS62480 in different core or I/O rail scenarios without hardware modification. All test data in the TPS62480EVM-671 User's Guide (SLVUAI6) was captured using these two settings.

How does the TPS62480EVM-671 handle high-current operation above 2 A?

The TPS62480EVM-671 uses dedicated high-current terminals to maintain signal integrity and minimize voltage drop at elevated loads. For input currents exceeding 2 A, J2 (VIN/GND terminal block) must be used instead of J1. For output currents above 2 A, J3 (VOUT/GND terminal block) is required instead of J4. These connectors ensure low-impedance paths and prevent overheating or measurement error during 6-A continuous operation - a key design feature confirmed in thermal test results (Figure 1, SLVUAI6).

What control signals are accessible on the TPS62480EVM-671 for system integration testing?

The TPS62480EVM-671 exposes all major control and monitoring pins of the TPS62480 IC via headers: EN (JP1), MODE (JP3), VSEL (JP2), SS/TR (J5), PG (J6), and TG (J7). Each pin has dedicated test points or jumper-configurable pullup options (JP4, JP5). This enables full validation of sequencing, fault reporting, tracking behavior, and mode transitions - essential for verifying interoperability with host controllers, PMICs, or FPGA management logic in final systems.

Is the TPS62480EVM-671 FCC-compliant for emissions testing?

The TPS62480EVM-671 is not FCC-certified as a standalone product. Per TI's Standard Terms and Conditions for Evaluation Modules, it is intended solely for R&D use in shielded environments or under experimental licenses. While the underlying TPS62480 IC meets relevant EMC specifications, the EVM's open-board layout and lack of enclosure mean it cannot be marketed or deployed as a finished device. Users must comply with FCC Part 15 rules - including interference mitigation and proper licensing - if operating the TPS62480EVM-671 outside controlled lab conditions.
