Texas Instruments TPS62932EVM

Overview

TPS62932EVM from Texas Instruments is an evaluation module for the TPS62932 2-A synchronous buck converter IC, configured to deliver a fixed 5-V output at up to 2 A from a 5.1–30-V input. It integrates the TPS62932DRLR in SOT583 package, features 500-kHz switching frequency, <20-mV_PP output ripple at 2-A load, and supports start-up, shutdown, and load transient testing with 20-MHz bandwidth measurement capability.

For engineers reviewing the TPS62932EVM datasheet, TPS62932EVM board layout, TPS62932EVM test setup, or TPS62932EVM schematic, this page provides verified performance data, jumper configuration guidance (JP1–JP4), test point mapping (TP1–TP18), and application-specific validation results including load transient response and output voltage ripple across 0–2-A loads.

Technical Context

The TPS62932EVM implements a complete, ready-to-test buck converter system centered on the TPS62932DRLR IC. It uses a 10-µH shielded inductor (Wurth 74439346100), input/output capacitors optimized for low ESR and high-frequency decoupling (including 22-µF X5R 1206 and 10-µF X7R 1206), and a fixed 5-V feedback network set by R4 = 53.6 kΩ.

Board-level features include configurable RT pin (JP1) for frequency selection, EN control via JP3, PGOOD/SS option via JP4, and VIN divider (JP2). Test points provide direct access to VIN, VOUT, SW node, EN, SS, PGOOD, and loop response analysis (TP10), enabling full characterization of line/load regulation, efficiency, and dynamic behavior.

FAQ

What is the primary function of the TPS62932EVM?

The TPS62932EVM is a fully assembled evaluation module that demonstrates and validates the performance of the TPS62932 2-A synchronous buck converter IC. It enables engineers to measure key parameters-including efficiency, load transient response, output ripple, start-up/shutdown behavior, and line regulation-without designing a custom PCB. The TPS62932EVM includes all necessary passive components, test points, and jumpers to configure and characterize the TPS62932 under real-world operating conditions.

How do I change the output voltage on the TPS62932EVM?

The TPS62932EVM is factory-configured for 5 V output using resistor R4 (53.6 kΩ). To adjust the output voltage, replace R4 with a new value calculated using the TPS62932 feedback divider equation: V_OUT = 0.8 V × (1 + R4/R5), where R5 = 10.2 kΩ. The schematic (Figure 6-1) and User's Guide Section 3.1 provide full calculation guidance and layout considerations for rework. No other resistor changes are required for standard output adjustments.

Which test points on the TPS62932EVM correspond to critical signals?

TP1 monitors VOUT (positive), TP2 is the VOUT power connection, TP3 monitors VIN (positive), TP4 is the VIN power connection, TP8 accesses the switch node (SW), TP11 monitors EN, TP12 monitors SS, and TP18 monitors PGOOD. Ground references include TP7, TP9, TP13–TP17. TP10 is dedicated to loop response (Bode plot) measurements. These test points are documented in Table 4-1 and Figure 4-1 of the TPS62932EVM User's Guide and are physically labeled on the board.

Can the TPS62932EVM be used for FCC pre-compliance testing?

No-the TPS62932EVM is not certified for EMC compliance and lacks shielding, filtering, or enclosure design required for FCC Part 15 submissions. It is intended solely for R&D feasibility evaluation per TI's Standard Terms for Evaluation Modules. While it supports 20-MHz bandwidth measurements useful for early-stage noise analysis, formal pre-compliance testing requires a final system-level design with proper layout, filtering, and mechanical integration-not the bare TPS62932EVM board.

What is the role of JP1, JP3, and JP4 on the TPS62932EVM?

JP1 selects the RT pin configuration to set switching frequency; JP3 connects EN to GND to disable the converter (open = enabled); JP4 selects between PGOOD or SS functionality on pin 7 of U1. These jumpers allow functional reconfiguration without soldering: JP1 enables frequency tuning, JP3 provides hardware enable/disable control, and JP4 determines whether the feedback network supports power-good indication or soft-start timing-each directly affecting how the TPS62932EVM interfaces with host systems during validation.
