Texas Instruments TPSM63603EVM

Overview

TPSM63603EVM from Texas Instruments is an evaluation module designed to demonstrate and validate the TPSM63603 36-V input, 1-V to 13-V output, 3-A synchronous-buck power module in real-world 3–36-V bus applications. It supports five selectable output voltages (2.5 V, 3.3 V, 5.0 V, 7.5 V, 12 V) and five switching frequencies (500 kHz to 2.0 MHz) via hardware jumpers, delivers full 3-A output current, and includes test points for efficiency, ripple, regulation, and transient response measurement.

For engineers reviewing the TPSM63603EVM datasheet, TPSM63603EVM pinout, TPSM63603EVM application, or TPSM63603EVM equivalent, this EVM enables rapid characterization of enable, synchronization, and power-good functionality; supports thermal and noise-optimized layout validation; and provides direct access to VIN/VOUT monitoring, EN/PGOOD/SYNC control signals, and UVLO configuration.

Technical Context

The TPSM63603EVM implements the TPSM63603 power module in a fully assembled, tested PCB with input/output capacitors sized for the full 3–36-V input range and all five output voltage options. Its layout follows TI's recommended thermal and EMI-optimized design, featuring dedicated Kelvin-sense traces for accurate efficiency measurement and low-inductance scope test points for ripple and transient analysis.

All control features - EN, SYNC, and PGOOD - are exposed via headers and test points with configurable pull-up/pull-down options. The board uses identical schematic, layout, and test point structure as the TPSM63603SEVM, differing only in the U1 IC (TPSM63603 vs. TPSM63603S), confirming its role as a dedicated platform for evaluating the base (non-spread-spectrum) variant.

FAQ

What is the primary function of the TPSM63603EVM?

The TPSM63603EVM is an evaluation module built around the TPSM63603 3-A synchronous-buck power module. Its primary function is to provide a ready-to-use platform for engineers to evaluate electrical performance-including efficiency, ripple, line/load regulation, and transient response-under real operating conditions across multiple input voltages, output voltages, and switching frequencies. The TPSM63603EVM enables hands-on validation before integrating the TPSM63603 into end equipment.

How do I configure the output voltage on the TPSM63603EVM?

The output voltage on the TPSM63603EVM is configured using the VOUT SELECT jumper (J6), which offers five fixed settings: 2.5 V, 3.3 V, 5.0 V, 7.5 V, and 12 V. Before applying input power, ensure the jumper is correctly installed on the corresponding pins per the User's Guide. The configuration directly sets the feedback network for the TPSM63603, eliminating need for external resistor changes during evaluation. Always power down before adjusting J6.

Can the TPSM63603EVM be synchronized to an external clock?

Yes, the TPSM63603EVM supports external clock synchronization via the SYNC test point. To use this feature, remove the ENABLE jumper (J5) first, then apply a clean CMOS-level clock signal to the SYNC point. This allows the TPSM63603 inside the TPSM63603EVM to lock its switching frequency to the external source, enabling EMI reduction through frequency alignment in multi-rail systems.

What test points are provided for measuring efficiency on the TPSM63603EVM?

The TPSM63603EVM provides dedicated Kelvin-sense test points VIN S+ / VIN S− and VOUT S+ / VOUT S− for precision efficiency measurement. These points connect directly to the input and output power paths with minimal trace resistance, allowing digital voltmeters to measure true input and output voltages under load without current-path voltage drop errors. Efficiency calculation requires simultaneous measurement of input/output voltage and current using these points and the terminal blocks (J1/J4).

Is the TPSM63603EVM compatible with the TPSM63603S device?

No - the TPSM63603EVM is specifically configured for the standard TPSM63603 power module (non-spread-spectrum). While the TPSM63603SEVM shares identical board layout, connectors, and test points, it uses the TPSM63603S variant with spread-spectrum modulation. Swapping U1 to TPSM63603S on the TPSM63603EVM is not supported or validated; TI provides separate part numbers (TPSM63603EVM vs. TPSM63603SEVM) to maintain design integrity and test repeatability.
