Texas Instruments TPSM5601R5EVM

Overview

TPSM5601R5EVM from Texas Instruments is an evaluation module designed to demonstrate and validate the TPSM5601R5 synchronous-buck power module, supporting 4.2–60-V input and configurable 1.2/1.8/2.5/3.3/5.0-V outputs at up to 1.5-A continuous load. It includes full input/output filtering, thermal-optimized PCB layout, and test points for efficiency, ripple, regulation, and transient response measurement in industrial and embedded power supply development.

For engineers reviewing the TPSM5601R5EVM datasheet, TPSM5601R5EVM pinout, TPSM5601R5EVM application, or TPSM5601R5EVM equivalent, this EVM enables rapid characterization of the TPSM5601R5 power module's startup/shutdown behavior, PGOOD signaling, EN control, line/load regulation, and spread-spectrum–free operation under real-world input voltage and load conditions.

Technical Context

The TPSM5601R5EVM implements a complete, ready-to-use buck converter reference design centered on the TPSM5601R5 integrated power module - a 60-V-input, 1.5-A output module with internal MOSFETs, controller, and compensation in a B3QFN package. It supports fixed-frequency PWM operation without spread spectrum (distinguishing it from the TPSM5601R5S variant).

Key board-level features include dual 4.7-µF/100-V input capacitors (C3/C4), four 100-µF/10-V output capacitors (C5–C8), VIN/VOUT terminal blocks rated for 16-AWG wire, and dedicated scope test points (J2/J3) with 0.1-in pitch for low-inductance probing of input/output ripple and transient waveforms.

FAQ

What is the primary function of the TPSM5601R5EVM?

The TPSM5601R5EVM is an evaluation module built around the TPSM5601R5 synchronous-buck power module. Its primary function is to provide a fully assembled, tested platform for engineers to evaluate electrical performance-including efficiency, ripple, regulation, and transient response-of the TPSM5601R5 under real operating conditions. The TPSM5601R5EVM does not replace production circuitry but serves as a validation tool prior to custom PCB design.

How do I configure the output voltage on the TPSM5601R5EVM?

The output voltage on the TPSM5601R5EVM is configured using the VOUT SELECT jumper (J6), a 5×2 header that selects among five preset values: 1.2 V, 1.8 V, 2.5 V, 3.3 V, or 5.0 V. Each setting corresponds to a specific pin pair on J6; the jumper must be installed before applying input power. Configuration requires no external resistors or soldering, enabling rapid retesting across common logic rail voltages.

Can the TPSM5601R5EVM be used to evaluate spread-spectrum operation?

No - the TPSM5601R5EVM is specifically populated with the TPSM5601R5 module, which operates in standard fixed-frequency PWM mode. Spread-spectrum functionality is exclusive to the TPSM5601R5S module, evaluated on the separate TPSM5601R5SEVM. The two EVMs share identical board layout and connectors, differing only in U1 (TPSM5601R5 vs. TPSM5601R5S) and silk-screen labeling.

What test equipment interfaces are supported by the TPSM5601R5EVM?

The TPSM5601R5EVM supports direct connection to digital multimeters (via VIN S+/S− and VOUT S+/S−) and oscilloscopes (via J2 and J3 scope test points). J2 and J3 use 0.1-in pitch sockets compatible with un-hooded probes and low-inductance ground springs. Additional control signals - EN, PGOOD, and PG_PU - are accessible via headers and test points for functional verification of enable sequencing and power-good assertion.

Is the TPSM5601R5EVM RoHS-compliant and suitable for industrial applications?

Yes - the TPSM5601R5EVM conforms to TI's standard RoHS-compliant manufacturing process and uses components qualified for industrial temperature operation. Its PCB layout follows TI's thermal and noise-reduction guidelines, and its 4.2–60-V input range, 1.5-A output capability, and robust input/output capacitance make it appropriate for evaluating power stages in programmable logic controllers, motor drives, and industrial IoT edge nodes.
