Texas Instruments TPS62866EVM-051

Overview

TPS62866EVM-051 from Texas Instruments is an evaluation module designed to characterize the TPS62866 6-A synchronous step-down converter with DCS-Control™, I²C interface, and 0.9-V fixed output (±1% accuracy) across 2.4–5.5-V input. It integrates a 220-nH power inductor, 10-µF/22-µF ceramic output capacitors, and supports real-time register programming via USB2ANY. Used for POL validation in AI accelerators and SSDs.

For engineers reviewing the TPS62866EVM-051 datasheet, TPS62866EVM-051 board layout, TPS62866EVM-051 GUI operation, or TPS62866EVM-051 I²C register map, this page delivers verified setup guidance, test-conditioned performance data, jumper-configurable VID/PG and EN control, and hardware/software interface details aligned with SLUUC21A Rev A.

Technical Context

The TPS62866EVM-051 implements a complete point-of-load evaluation platform for the TPS62866 IC in 1.05-mm × 1.78-mm WCSP packaging. It provides direct access to VIN, VOUT, S+/S− sense lines, and I²C (SCL/SDA) signals through labeled headers J1–J3, enabling precision voltage measurement and closed-loop configuration.

Board-level features include dual 22-µF X7R output capacitors (C2/C3), 68-µF tantalum bulk capacitor (C8), 100-kΩ and 86.6-kΩ resistors for I²C pull-up and address setting, and JP1/JP2 jumpers for VID/PG selection and EN enable/disable - all matching the TPS62866's operational requirements per SLVSEI1.

FAQ

What is the primary function of the TPS62866EVM-051?

The TPS62866EVM-051 is a fully assembled evaluation module that enables functional and performance validation of the TPS62866 6-A step-down converter. It provides immediate access to input/output power paths, I²C configuration, and real-time telemetry - eliminating prototype PCB development for early-stage AI and storage system design. The TPS62866EVM-051 includes all critical passive components and jumper-selectable control logic required to operate the underlying TPS62866 IC out of the box.

How do I configure the output voltage on the TPS62866EVM-051?

The TPS62866EVM-051 defaults to 0.9-V fixed output via internal resistor divider. Voltage can be dynamically adjusted between 0.4 V and 1.675 V using the GUI's Settings screen to write to VOUT Register 1 or Register 2 - selection depends on JP1 position (VID/PG to LOW or HIGH). The TPS62866EVM-051 does not support external resistor programming; all adjustments require I²C communication via USB2ANY or compatible host.

Which interface hardware is required to communicate with the TPS62866EVM-051?

The TPS62866EVM-051 requires the TI USB2ANY interface board (TI part # USB2ANY) and a keyed 10-pin ribbon cable to establish I²C communication with a Windows PC. J3 header provides dedicated SCL, SDA, VBUS, and GND connections. VBUS may be left unconnected since USB2ANY supplies its own 3.3-V bias - no external level shifters or pull-up resistors are needed for basic operation of the TPS62866EVM-051.

Can the TPS62866EVM-051 be used to evaluate multiple TPS62866 variants?

Yes - the TPS62866EVM-051 is designed to support the full TPS62864/6 family. Its schematic accommodates different TPS62866 variants via U1 socket compatibility (DSBGA-15 footprint), and the GUI supports register-level configuration common across the family. However, output current capability and thermal behavior must be validated per specific variant's datasheet limits - the TPS62866EVM-051 layout is optimized for the 6-A TPS62866, not lower-current derivatives.

Where can I find the Gerber files and schematic for the TPS62866EVM-051?

Gerber files, the full schematic (Figure 5-1), and Bill of Materials (Table 5-1) for the TPS62866EVM-051 are published in the official User's Guide SLUUC21A (Rev A, July 2021) on ti.com.
