Texas Instruments TPSM82816PEVM-062

Overview

TPSM82816PEVM-062 from Texas Instruments is a dedicated evaluation module for the TPSM82816PVCAR 6A step-down power module with integrated inductor and frequency synchronization, configured for 1.8V output at ±1% accuracy across 2.7V–6V input. It implements MagPack™ packaging (2.5mm × 3mm × 1.95mm), supports >3A load via J1/J2 high-current headers, and enables loop response measurement, soft-start tuning, and precise enable-threshold configuration.

For engineers reviewing the TPSM82816PEVM-062 datasheet, TPSM82816PEVM-062 hardware design files, TPSM82816PEVM-062 schematic, or TPSM82816PEVM-062 thermal performance data, this EVM provides validated test points (SW, PG, SS/TR), jumper-configurable MODE/SYNC and EN logic, and Gerber files for four-layer 2-ounce copper PCB replication - all critical for POL power validation in space-constrained systems.

Technical Context

The TPSM82816PEVM-062 implements a complete, pre-layout-verified buck converter reference design centered on the TPSM82816PVCAR IC. It includes input/output sensing (J5/J6 S+/S–), programmable soft-start (C4), external clock synchronization (J4 pin 2), and precision enable threshold adjustment (JP1 removed + R5/R7).

Hardware features include dual high-current interfaces (J1 for VIN ≥3A, J2 for VOUT ≥3A), thermal performance validation (θJA = 26.6 °C/W at 5V_IN/1.8V_OUT/6A), and loop stability analysis capability via R1/C6 injection point - enabling direct measurement of gain/phase margins per Figure 3-3.

FAQ

What is the primary function of the TPSM82816PEVM-062?

The TPSM82816PEVM-062 is an evaluation module built to validate the electrical, thermal, and dynamic performance of the TPSM82816PVCAR 6A step-down power module. It provides a fully assembled, tested reference design with accessible test points, configurable jumpers, and documented thermal/measurement results - enabling engineers to verify voltage regulation accuracy, transient response, loop stability, and thermal behavior before integrating into final systems.

Does the TPSM82816PEVM-062 support external frequency synchronization?

Yes, the TPSM82816PEVM-062 supports external frequency synchronization via the MODE/SYNC pin, accessible at J4 pin 2. When JP2 is removed, the MODE/SYNC signal accepts an external clock source to align switching frequency with system timing requirements - a key feature for noise-sensitive applications like high-speed data converters or RF front-ends where spectral interference must be controlled.

How is output voltage accuracy verified on the TPSM82816PEVM-062?

Output voltage accuracy on the TPSM82816PEVM-062 is verified as ±1% at 1.8V across the full 0–6A load range and 2.7V–6V input range. This specification is confirmed using the dedicated output sense connections (J6 pins 3–4, S+/S–), which provide Kelvin-sense feedback independent of current-carrying traces - ensuring measurement fidelity matches actual load-point regulation performance of the TPSM82816PVCAR device.

Can the TPSM82816PEVM-062 be used to evaluate thermal performance under full load?

Yes, the TPSM82816PEVM-062 is explicitly characterized for thermal performance at full 6A load: Figure 3-1 in the user guide documents θJA = 26.6 °C/W at 5V_IN/1.8V_OUT/6A. The board uses 2-ounce copper across all four layers to maximize heat spreading, and its layout accommodates direct IR imaging or thermocouple placement on the TPSM82816PVCAR package - enabling realistic junction temperature estimation for thermal margining in end equipment.

What are the key hardware modifications supported by the TPSM82816PEVM-062?

The TPSM82816PEVM-062 supports multiple user-modifiable features: soft-start time adjustment via C4, switching frequency and loop compensation tuning via R4, spread spectrum enable/disable (TPSM82816 only), additional input/output capacitance (C7, C8–C10), and precise enable-threshold configuration using R5/R7 when JP1 is removed. These options allow engineers to tailor dynamic response, EMI profile, and startup behavior to match specific application constraints without redesigning the core power stage.
