Texas Instruments TPSM8287A15BBHEVM

Overview

TPSM8287A15BBHEVM from Texas Instruments is a dedicated evaluation module for the TPSM8287A15BBHRDWR 15A synchronous step-down power module, enabling rapid validation of high-accuracy point-of-load (POL) regulation in FPGA core supplies, ASIC rails, and DDR memory applications. It supports 2.7V–6V input, 0.4V–3.35V adjustable output, I²C programmability, remote sensing, and parallel operation.

For engineers reviewing the TPSM8287A15BBHEVM datasheet, TPSM8287A15BBHEVM hardware design files, TPSM8287A15BBHEVM GUI integration, or TPSM8287A15BBHEVM thermal performance under 15A load, this EVM provides validated test points, jumper-configurable startup voltage, SMA-based ripple measurement, and full schematic/PCB layout access for production-ready power stage characterization.

Technical Context

The TPSM8287A15BBHEVM implements the TPSM8287A15BBHRDWR power module in a stand-alone, non-paralleled configuration per default, with provisions for multi-module synchronization via SYNC_OUT and MODE/SYNC pin control. It integrates remote sense (VOSNS/GOSNS), precision enable threshold tuning (via R2/R18), and I²C interface (SCL/SDA) routed to J5 for GUI-based voltage/frequency/compensation adjustment.

Hardware-level features include dual-input/output terminal options (J1/MH1–MH4), PG status monitoring at J3, SW node test point (TP5), and configurable VSET1–VSET3 jumpers supporting 59 discrete startup voltages - all mapped directly to the underlying IC's I²C address table and internal DAC resolution.

FAQ

What is the primary function of the TPSM8287A15BBHEVM?

The TPSM8287A15BBHEVM is an evaluation module built around the TPSM8287A15BBHRDWR 15A power module. Its primary function is to accelerate development and validation of high-accuracy, digitally controlled point-of-load power supplies - providing ready-to-use hardware for measuring efficiency, thermal behavior, transient response, and I²C programmability without custom PCB design. The TPSM8287A15BBHEVM includes all necessary passive components, test points, and jumper-based configuration for immediate bench testing.

Does the TPSM8287A15BBHEVM support parallel operation of multiple modules?

Yes, the TPSM8287A15BBHEVM supports parallel operation through its SYNC_OUT signal (J4 pin 1) and MODE/SYNC pin (U1 pin 29), enabling synchronization of switching frequency across multiple TPSM8287A modules. While the board itself hosts only one TPSM8287A15BBHRDWR IC, its design includes routing and header access for inter-module clock sharing and current-sharing configurations - as confirmed in the EVM User's Guide section on paralleling capability.

How is output voltage adjusted on the TPSM8287A15BBHEVM?

Output voltage on the TPSM8287A15BBHEVM is adjusted via three methods: (1) hardware jumpers JP4–JP9 for 59 fixed startup voltages (0.4V–3.35V), (2) I²C commands through J5 using the TPSM8287Axx EVM GUI for fine-grained post-startup tuning, and (3) external resistor divider on EN pin (R2/R18) for precise turn-on threshold control. All methods are fully supported and documented for the TPSM8287A15BBHEVM in SLUUCV0B.

What thermal performance can be expected from the TPSM8287A15BBHEVM at full 15A load?

At VIN = 5V, VOUT = 0.9V, and IOUT = 15A, the TPSM8287A15BBHEVM achieves a measured θJA of 19.5°C/W, as shown in Figure 4-4 of the EVM User's Guide. This performance is enabled by the 4.5mm × 6.8mm overmolded QFN package, 2-ounce copper PCB layers, and optimized thermal pad layout - allowing sustained 15A operation without forced airflow in typical lab environments.

Is a separate adapter required to use the I²C interface on the TPSM8287A15BBHEVM?

Yes - the TPSM8287A15BBHEVM requires the USB2ANY adapter EVM (ordered separately) to connect J5 (10-pin I²C header) to a host PC for communication with the TPSM8287Axx EVM GUI. The EVM operates standalone without I²C, but GUI-based voltage/frequency/compensation control, telemetry readback, and real-time monitoring of the TPSM8287A15BBHRDWR IC require this adapter and associated software.
