Texas Instruments TPSM84205EVM-888

Overview

TPSM84205EVM-888 from Texas Instruments is an evaluation module designed to demonstrate the TPSM84205 5.0 V, 1.5-A synchronous buck power module in a compact 3-pin TO-220 footprint. It supports input voltages from 7.0 V to 28 V, delivers fixed 5.0 V output, and includes test points for efficiency, ripple, load regulation, and transient response measurement. The EVM uses TI's recommended PCB layout to maximize thermal performance and minimize noise.

For engineers reviewing the TPSM84205EVM-888 datasheet, TPSM84205EVM-888 pinout, TPSM84205EVM-888 application, or TPSM84205EVM-888 equivalent, this page provides verified technical context, key specifications, supply support, and design-specific FAQs - all focused on rapid validation of the TPSM84205 power module in industrial, embedded, and point-of-load applications.

Technical Context

The TPSM84205EVM-888 implements a complete evaluation platform for the TPSM84205 power module, which integrates MOSFETs, shielded inductor, and passive components into a single surface-mount package. It operates at a fixed 500 kHz switching frequency and supports up to 1.5 A continuous output current with input voltage range 7.0 V–28 V.

Test points TP1 (VIN), TP2 (GND), and TP3 (VOUT) enable precise DC voltage monitoring, while J2 (VIN MON) and J3 (VOUT MON) provide low-inductance oscilloscope access for ripple and transient analysis. The board includes pre-mounted 4×47 µF ceramic + 2×470 µF polymer output capacitance and footprints for additional filtering on both input and output sides.

FAQ

What is the primary function of the TPSM84205EVM-888?

The TPSM84205EVM-888 is an evaluation module built to validate the performance and implementation of the TPSM84205 5.0 V, 1.5-A synchronous buck power module. It provides accessible test points, optimized layout, and pre-populated passives to accelerate design-in and reduce risk during early-stage power system development. The TPSM84205EVM-888 itself is not a production power solution but a reference platform for engineering verification.

Does the TPSM84205EVM-888 support adjustable output voltage?

No. The TPSM84205EVM-888 is configured exclusively for the TPSM84205 device, which delivers a fixed 5.0 V output. Unlike programmable modules, it does not include external feedback resistors or voltage-setting components. Output voltage adjustment requires a different module variant - such as the TPSM84203 (3.3 V) or TPSM84212 (12.0 V) - each with its own dedicated EVM version (TPSM84203EVM-888 or TPSM84212EVM-888).

Can the TPSM84205EVM-888 be used with input voltages below 7.0 V?

No. The TPSM84205EVM-888 is designed specifically for the TPSM84205 power module, whose absolute minimum input voltage is 7.0 V per its datasheet. Applying less than 7.0 V will prevent proper startup or cause erratic regulation. For lower-input applications, engineers should evaluate the TPSM84203EVM-888 (4.5 V–28 V input range) instead.

What test equipment interfaces are provided on the TPSM84205EVM-888?

The TPSM84205EVM-888 includes three wire-loop test points (TP1 = VIN, TP2 = GND, TP3 = VOUT) for DC multimeter measurements, and two dual-pin scope probe sockets (J2 = VIN MON, J3 = VOUT MON) with 0.1-inch spacing and ground-spring compatibility. These interfaces allow direct, low-noise measurement of efficiency, ripple, line/load regulation, and transient response without soldering or signal injection.

Is the TPSM84205EVM-888 RoHS-compliant and certified for EMC testing?

Yes. The TPSM84205EVM-888 complies with RoHS Directive 2011/65/EU and is classified as a Class A digital device under EU Directive 2014/30/EU (EMC). As stated in its user guide, it is intended for lab-based R&D use only and must be operated in non-domestic environments. FCC compliance is not granted for end-product integration - users must perform final-system EMC validation separately.
