Texas Instruments TPS62902-Q1EVM

Overview

TPS62902-Q1EVM from Texas Instruments is an automotive-grade evaluation module for the TPS62902-Q1 3-V to 18-V, 2-A synchronous buck converter with DCS-Control topology, ±1.5% output voltage accuracy, 4-µA quiescent current, and operation up to +165°C junction temperature - designed for validating power delivery in ADAS and infotainment systems.

For engineers reviewing the TPS62902-Q1EVM datasheet, TPS62902-Q1EVM setup guide, TPS62902-Q1EVM test configuration, or TPS62902-Q1EVM compatibility with TPS62902-Q1 design files, this module enables rapid functional validation, efficiency measurement, transient response characterization, and AEC-Q100-compliant thermal stress testing under real automotive input conditions (3–18 V) and load profiles (0–2 A).

Technical Context

The TPS62902-Q1EVM implements the full reference design of the TPS62902-Q1 IC in a 2.2-mm × 2.0-mm VQFN-9 (RYT) package, supporting both adjustable (FB) and fixed-output (VSET) configurations via onboard jumpers and resistor options. It integrates all critical external components: 1-µH shielded inductor, 10-µF/22-µF ceramic output capacitors, input bulk capacitor, and precision soft-start/tracking network.

It exposes all key control signals - EN, MODE/S-CONF, SS/TR, PG, and VOS - for mode selection (1 MHz / 2.5 MHz, forced PWM / auto PFM), output discharge enable, power-good monitoring, and sequencing validation. The board is optimized for single-layer routing and includes thermal vias aligned to the IC's exposed pad for reliable +165°C TJ operation.

FAQ

What is the primary purpose of the TPS62902-Q1EVM?

The TPS62902-Q1EVM is a fully assembled and tested evaluation module for the TPS62902-Q1 automotive buck converter. It enables engineers to validate electrical performance - including efficiency, transient response, thermal behavior, and functional modes - without designing custom PCBs. The board supports both FB-based adjustable outputs and VSET-based fixed outputs, and provides access to all control pins for system integration testing.

Does the TPS62902-Q1EVM support both 1-MHz and 2.5-MHz switching frequencies?

Yes, the TPS62902-Q1EVM supports both 1-MHz and 2.5-MHz operation via the MODE/S-CONF pin configuration. Jumper settings or external resistors on the board allow selection of switching frequency, PFM/PWM mode, output discharge, and internal/external feedback - matching the full configurability of the underlying TPS62902-Q1 IC as specified in Table 8-1 of its datasheet.

Can the TPS62902-Q1EVM be used to verify +165°C junction temperature operation?

Yes, the TPS62902-Q1EVM is designed to support validation up to +165°C junction temperature. Its layout includes thermal vias under the TPS62902-Q1's exposed pad and follows TI's recommended thermal land pattern. When mounted on a standard JEDEC PCB, it achieves RθJB = 28°C/W and RθJA = 73.5°C/W - enabling controlled thermal stress testing consistent with AEC-Q100 Grade 1 requirements.

Is WEBENCH® Power Designer compatible with the TPS62902-Q1EVM design?

Yes, the TPS62902-Q1EVM reference design is integrated into TI's WEBENCH® Power Designer tool. Users can import the TPS62902-Q1EVM schematic, simulate performance across input/output conditions, generate BOMs, and compare against alternate converters - ensuring design consistency between simulation, evaluation, and final production layouts for the TPS62902-Q1.

What output voltage options does the TPS62902-Q1EVM support out-of-the-box?

The TPS62902-Q1EVM supports both externally adjustable outputs (0.6 V to 5.5 V via FB divider) and 16 factory-selectable fixed outputs (0.4 V to 5.5 V) using the VSET resistor network. Onboard jumpers and populated resistor footprints allow quick reconfiguration - for example, default VSET option yields 3.3 V or 5.0 V depending on RVSET selection - aligning with common automotive rail requirements.
