Texas Instruments TPS54J060EVM-067

Overview

TPS54J060EVM-067 from Texas Instruments is an evaluation module designed to demonstrate the performance and configuration flexibility of the TPS54J060 6-A synchronous buck converter. It supports input voltages from 4 V to 16 V, delivers a default 1.8-V output, operates at up to 1100 kHz switching frequency in forced continuous conduction mode (FCCM), and features D-CAP3™ control topology with no external compensation required.

For engineers reviewing the TPS54J060EVM-067 datasheet, TPS54J060EVM-067 test setup, TPS54J060EVM-067 load transient response, or TPS54J060EVM-067 soft-start configuration, this EVM provides validated reference design data-including efficiency curves, loop bandwidth (103 kHz), phase margin (72.6°), output ripple (5 mVPP at 6 A), and jumper-selectable operation modes-to accelerate power stage validation for industrial and embedded DC/DC applications.

Technical Context

The TPS54J060EVM-067 implements the TPS54J060 IC in a fully assembled, tested PCB layout optimized for minimal footprint and thermal performance. It integrates high-side and low-side MOSFETs, uses a D-CAP3™ adaptive on-time control architecture enabling fast transient response (<10 µs recovery), and supports dual power-up sequences-EN-controlled and VIN-ramp-with pre-bias start-up capability.

Configuration is hardware-driven via jumpers: J3 selects EN biasing (open = VIN-referenced divider; shorted = grounded), J4 sets switching frequency (600/1100/2000 kHz) and light-load mode (FCCM or DCM), while R3/R7 resistor divider adjusts output voltage using device-specific internal references (0.9 V for TPS54J060).

FAQ

What is the primary function of the TPS54J060EVM-067?

The TPS54J060EVM-067 is an evaluation module that demonstrates the electrical performance, thermal behavior, and configuration options of the TPS54J060 6-A synchronous buck converter. It is not a production power supply but a validated reference design used for bench testing, schematic review, layout verification, and dynamic characterization-including efficiency mapping, load transient response, and loop stability analysis-prior to custom board integration.

Does the TPS54J060EVM-067 support adjustable output voltage?

Yes, the TPS54J060EVM-067 supports adjustable output voltage via the R3/R7 feedback resistor divider. With the TPS54J060's internal reference of 0.9 V, changing R3 while holding R7 fixed allows precise setting of V_OUT above 0.9 V. The user's guide provides Equation 1 for calculating R3 based on target output voltage, and the EVM is shipped configured for 1.8 V.

How is switching frequency and operation mode selected on the TPS54J060EVM-067?

Switching frequency and operation mode (FCCM or DCM) are selected using jumper J4, which connects the MODE pin to different resistor values tied to AGND or VCC. Six configurations are supported-including 1100 kHz FCCM (default, pins 11–12 shorted) and 1100 kHz DCM (pins 1–2 shorted)-as detailed in Table 1-3 of the user's guide. Each setting directly configures the D-CAP3™ controller's timing and light-load behavior.

Can the TPS54J060EVM-067 be used with input voltages below 4 V?

No-the TPS54J060EVM-067 is validated for input voltages from 4 V to 16 V per Table 1-1. While the underlying TPS54J060 IC may operate down to ~2.95 V, the EVM's component selection (e.g., input capacitors, current-sense resistors, UVLO divider) and thermal design are optimized for ≥4 V. Operation below 4 V requires redesign of the UVLO network and validation of startup, regulation, and thermal margins.

What test points are available on the TPS54J060EVM-067 for measurement and probing?

The TPS54J060EVM-067 provides dedicated test points including VIN_SNS+/VIN_SNS− (input voltage sensing), VOUT/PGND (output voltage monitoring), PGOOD (power-good status), EN (enable signal), MODE (mode pin voltage), SW (switch node), BODE+/BODE− (loop gain/phase measurement), and AGND. These enable comprehensive characterization-efficiency, ripple, transient response, loop stability, and startup sequencing-without soldering or modification.
