Texas Instruments TPS54J061EVM-067

Overview

TPS54J061EVM-067 from Texas Instruments is an evaluation module designed to demonstrate the performance of the TPS54J061 6-A synchronous buck converter, configured for 1.8-V output with 4–16-V input range, FCCM/DCM mode selection via MODE jumper, and D-CAP3™ control topology requiring no external compensation.

For engineers reviewing the TPS54J061EVM-067 datasheet, TPS54J061EVM-067 pinout, TPS54J061EVM-067 application, or TPS54J061EVM-067 equivalent, key selection considerations include adjustable UVLO via EN resistor divider, 1.5-ms soft-start time (TPS54J061-specific), valley current limit set to 6 A, and support for both internal and external 3.3-V VCC biasing.

Technical Context

The TPS54J061EVM-067 implements the TPS54J061 IC in a fully assembled, tested PCB layout optimized for thermal performance and minimal board area. It integrates high-side and low-side MOSFETs, supports D-CAP3™ adaptive on-time control, and enables operation in either Forced Continuous Conduction Mode (FCCM) or Discontinuous Conduction Mode (DCM) via configurable MODE pin connections.

Key test-access features include dedicated BODE+ and BODE− points for loop analysis, VIN_SNS+/VIN_SNS− for input voltage monitoring, and jumper-selectable enable (J3) and mode (J4) configurations. The module uses a 0.6-V internal reference (TPS54J061-specific), enabling tighter output regulation and faster soft-start versus the TPS54J060's 0.9-V reference.

FAQ

What is the purpose of the TPS54J061EVM-067?

The TPS54J061EVM-067 is an evaluation module built around the TPS54J061 6-A synchronous buck converter. It provides a ready-to-use platform for testing efficiency, transient response, loop stability, and configuration options-including FCCM/DCM mode, adjustable UVLO, and soft-start-without requiring custom PCB design. Engineers use the TPS54J061EVM-067 to validate power architecture before committing to production layouts.

How does the TPS54J061EVM-067 differ from the TPS54J060EVM-067?

The TPS54J061EVM-067 uses the TPS54J061 IC with a 0.6-V internal reference, resulting in a shorter 1.5-ms soft-start time and slightly higher light-load efficiency due to its higher-resistance feedback divider. In contrast, the TPS54J060EVM-067 uses a 0.9-V reference and 2-ms soft-start. Both share identical input/output ranges, layout, and jumper-based configuration options.

Can the output voltage of the TPS54J061EVM-067 be adjusted?

Yes, the output voltage of the TPS54J061EVM-067 is adjustable via the R3/R7 resistor divider network. With R7 fixed, changing R3 recalculates the output using V_OUT = V_INTREF × (1 + R3/R7), where V_INTREF = 0.6 V for the TPS54J061. This allows reconfiguration to common rails such as 1.2 V, 1.5 V, or 3.3 V without hardware redesign.

What are the supported switching frequency and operation modes on the TPS54J061EVM-067?

The TPS54J061EVM-067 supports six combinations via J4: 600 kHz or 1100 kHz or 2000 kHz, each configurable for either Forced CCM or Skip Mode (DCM). Default is 1100 kHz in DCM (jumper pins 1–2 shorted). Mode selection directly impacts light-load efficiency, output ripple, and EMI profile-enabling optimization for specific application requirements.

Does the TPS54J061EVM-067 require external compensation components?

No, the TPS54J061EVM-067 requires no external compensation components because it implements TI's D-CAP3™ control topology. This adaptive on-time architecture senses output voltage ripple for instantaneous response and inherently stabilizes the control loop across varying input, load, and output capacitor conditions-reducing design complexity and BOM count.
