Texas Instruments TPSM8287A10BAHEVM

Overview

TPSM8287A10BAHEVM from Texas Instruments is an evaluation module designed to characterize the TPSM8287A10BAHRDWR 10A synchronous step-down power module with I²C interface, remote sensing, and frequency synchronization. It supports input voltages from 2.7V to 6V, delivers adjustable output voltage from 0.4V to 3.35V (±0.8% accuracy), and enables thermal, loop response, and ripple measurements in point-of-load applications.

For engineers reviewing the TPSM8287A10BAHEVM datasheet, TPSM8287A10BAHEVM hardware design files, TPSM8287A10BAHEVM test setup, or TPSM8287A10BAHEVM GUI integration with USB2ANY, this EVM provides validated reference schematics, Gerber files, BOM, and measurement procedures for rapid POL converter validation in FPGA core, ASIC, DDR, and optical module power designs.

Technical Context

The TPSM8287A10BAHEVM implements a complete, stand-alone buck converter test platform using the TPSM8287A10BAHRDWR IC - a pin-to-pin compatible member of the 6A/10A/12A/15A TPSM8287Axx family. It integrates all passive components except bulk output capacitance and supports both fixed-voltage operation and I²C-programmable VOUT via jumper-selectable VSET pins or real-time GUI control.

Hardware features include dual input/output terminal options (screw terminals MH1–MH4 and headers J1/J2), dedicated SMA output voltage probe (J6), SYNC_OUT signal header (J4), power-good monitoring (J3), and configurable MODE/SYNC and EN logic via jumpers JP2 and JP1. Loop response measurement is enabled by replacing R5 with a 10Ω injection resistor.

FAQ

What is the primary function of the TPSM8287A10BAHEVM?

The TPSM8287A10BAHEVM is an evaluation module used to validate the electrical, thermal, and dynamic performance of the TPSM8287A10BAHRDWR 10A synchronous step-down power module. It provides a ready-to-use PCB with test points, headers, and jumper-based configuration to evaluate startup behavior, load regulation, ripple, loop stability, and I²C programmability without custom design effort.

Does the TPSM8287A10BAHEVM require the USB2ANY adapter to operate?

No - the TPSM8287A10BAHEVM operates as a standalone buck converter without any external interface. The USB2ANY adapter (ordered separately) is only required to access the I²C interface for real-time VOUT adjustment, telemetry, and GUI-based configuration via the TPSM8287Axx EVM GUI software.

How is output voltage set on the TPSM8287A10BAHEVM?

Output voltage is set using three 3-position jumpers (JP4/JP7, JP5/JP8, JP6/JP9) that select one of 59 discrete VOUT values between 0.4V and 3.35V. These jumpers configure the VSET1/VSET2/VSET3 inputs to the TPSM8287A10BAHRDWR IC before VIN is applied; changing them during operation has no effect.

What thermal performance data is available for the TPSM8287A10BAHEVM?

Figure 4-3 in the user's guide documents thermal performance for the TPSM8287A10BAHEVM under VIN = 5V, VOUT = 0.9V, and IOUT = 10A conditions. Measured θJA is 19.5°C/W on the BSR259 reference board, confirming suitability for high-current, low-profile POL applications with constrained airflow.

Can multiple TPSM8287A10BAHEVM units be paralleled for higher current?

No - the TPSM8287A10BAHEVM itself is not designed for paralleling. However, the underlying TPSM8287A10BAHRDWR IC supports current sharing and synchronization when implemented in a custom paralleled design. The EVM is intended for single-module evaluation only, as stated in Section 1.2 ("stand-alone, not paralleled" application).
