Texas Instruments TPS84620EVM-692

Overview

TPS84620EVM-692 from Texas Instruments is an evaluation module designed to demonstrate the TPS84620 integrated 3-A synchronous buck power module in a compact, ready-to-use PCB format. It supports input voltage range of 4.5 V to 14.5 V (PVIN = VIN), delivers adjustable output voltages from 1.2 V to 5.5 V, and operates at switching frequencies from 480 kHz to 780 kHz - validated for use in FPGA and DSP point-of-load applications.

For engineers reviewing the TPS84620EVM-692 datasheet, TPS84620EVM-692 pinout, TPS84620EVM-692 application, or TPS84620EVM-692 equivalent, this page provides verified electrical specifications, test setup guidance, performance curves (including 12 mV peak-to-peak ripple at 3.3 V/6 A), layout notes, and jumper-based configuration options for voltage, frequency, slow start, tracking, and UVLO.

Technical Context

The TPS84620EVM-692 implements the TPS84620 QFN-packaged SWIFT™ power module - integrating high-side and low-side MOSFETs, gate drivers, PWM controller, and internal compensation. It uses dual-input architecture (PVIN and VIN), though the EVM defaults to single-supply operation via J3 jumper (VIN = PVIN).

Key operational features include remote sense (SENSE+ on pin 44), adjustable soft-start (via C8 and J10), external track-in capability (J6/J5), programmable UVLO (J8), and SYNC input (TP14) supporting frequency synchronization from 480 kHz to 780 kHz. The board is optimized for minimal footprint (354 mm²) and thermal performance with AGND–PGND single-point connection and dedicated heat-transfer vias at AGND terminal 45.

FAQ

What is the maximum input voltage rating for the TPS84620EVM-692?

The TPS84620EVM-692 has an absolute maximum input voltage of 15 V. Its operational input range is specified as 4.5 V to 14.5 V when PVIN and VIN are tied together (default J3 position). Exceeding 15 V may cause irreversible damage to the TPS84620RUQ module or surrounding components on the board.

Can the TPS84620EVM-692 be used to evaluate the TPS84621 or TPS84320 devices?

No - the TPS84620EVM-692 is hardware-specific to the TPS84620RUQ module (3-A rated). While it shares mechanical layout and jumper architecture with the TPS84320EVM-692 and TPS84621EVM-692, the U1 component placement, current-sense network, and thermal design are optimized for the TPS84620's 3-A capability. Substituting other modules requires verification per SLVU415A Section 4.

How do I adjust the output voltage on the TPS84620EVM-692?

Output voltage is adjusted using either J4 (predefined voltage selection: 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, or 5 V) or by replacing one of the RSET resistors (R2–R6 or R8) with a value calculated from the TPS84620 datasheet's V_OUT = 0.765 V × (1 + R_SET/10 kΩ) equation. Default setting (all J4 jumpers open) yields no fixed output - resistor selection required.

Does the TPS84620EVM-692 support remote sensing?

Yes - the TPS84620EVM-692 implements remote sensing via the SENSE+ pin (U1 pin 44), routed to TP5 and J7 pin 2. To enable, connect the SENSE+ trace directly to the load's V_OUT node and replace R1 with a 49.9 Ω resistor (per SLVU415A Section 5.1 and Figure 13 layout note).

What safety and compliance status applies to the TPS84620EVM-692?

The TPS84620EVM-692 is an engineering evaluation tool intended solely for lab use - not certified for CE, FCC, UL, RoHS, or WEEE compliance. TI explicitly states it falls outside EU directives and FCC Part 15 limits. Users must implement appropriate ESD precautions, thermal monitoring, and input/output voltage limiting per the Warnings and Restrictions section of SLVU415A.
