Texas Instruments TPSM5601R5SEVM

Overview

TPSM5601R5SEVM from Texas Instruments is an evaluation module for the TPSM5601R5S synchronous-buck power module with spread-spectrum frequency modulation, designed for 4.2-V to 60-V input bus applications and configurable 1.2-V to 5.0-V output voltages. It delivers full 1.5-A output current, includes input/output capacitors for full-range operation, and provides test points for efficiency, ripple, regulation, and transient response measurement.

For engineers reviewing the TPSM5601R5SEVM datasheet, TPSM5601R5SEVM pinout, TPSM5601R5SEVM application, or TPSM5601R5SEVM equivalent, this EVM enables rapid validation of spread-spectrum EMI reduction, enable/power-good control, and thermal performance in industrial and automotive power supply designs.

Technical Context

The TPSM5601R5SEVM implements a complete reference design for the TPSM5601R5S power module, featuring a B3QFN package with integrated MOSFETs, controller, and compensation. It supports five fixed output voltages via jumper-selectable feedback network and includes dedicated test points for EN, PGOOD, VIN, and VOUT monitoring.

Spread-spectrum operation is enabled by default on the TPSM5601R5S device mounted on this board, reducing peak EMI emissions without external components. The PCB layout follows TI's recommended thermal and noise-minimization guidelines, with dedicated signal layers and optimized ground planes.

FAQ

What is the primary function of the TPSM5601R5SEVM?

The TPSM5601R5SEVM is an evaluation module for the TPSM5601R5S synchronous-buck power module. Its primary function is to provide a ready-to-use platform for validating the electrical performance, thermal behavior, and EMI characteristics of the TPSM5601R5S in real-world 4.2-V to 60-V input applications. Engineers use the TPSM5601R5SEVM to measure efficiency, ripple, load/transient response, and spread-spectrum effectiveness without designing custom hardware.

How does the TPSM5601R5SEVM differ from the TPSM5601R5EVM?

The TPSM5601R5SEVM differs from the TPSM5601R5EVM solely in the mounted power module: TPSM5601R5SEVM uses the TPSM5601R5S (with integrated spread-spectrum operation), while TPSM5601R5EVM uses the standard TPSM5601R5. All other aspects-including PCB layout, test points, jumpers, connectors, and BOM-are identical. The silk screen labeling also reflects the respective module variant.

Which output voltages can be configured on the TPSM5601R5SEVM?

The TPSM5601R5SEVM supports five discrete output voltages: 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V. Selection is made using the VOUT SELECT jumper (J6), a 5×2 header located near the output terminal block. Each configuration routes the appropriate feedback resistor network to set the regulated output voltage per the TPSM5601R5S internal reference and compensation scheme.

Does the TPSM5601R5SEVM support enable and power-good functionality?

Yes, the TPSM5601R5SEVM fully supports both enable and power-good functions. The ENABLE Control header (J5) allows manual on/off control via jumper position. The PGOOD test point provides access to the open-drain power-good signal, and the PG_PU test point enables connection of an external pullup voltage. A built-in 49.9-kΩ resistor connects these two points, matching the recommended interface per the TPSM5601R5S datasheet.

What test points are provided for measuring input and output ripple on the TPSM5601R5SEVM?

The TPSM5601R5SEVM provides dedicated scope-compatible test points: VIN Scope (J2) for input voltage ripple and VOUT Scope (J3) for output voltage ripple and transient response. Both consist of 0.1-in spaced sockets intended for un-hooded oscilloscope probes with low-inductance ground springs. These points are isolated from high-current paths to preserve signal integrity during measurement of the TPSM5601R5SEVM's switching waveforms.
