Texas Instruments TPS562242EVM

Overview

TPS562242EVM from Texas Instruments is an evaluation module for the TPS562242 synchronous buck converter IC, configured to deliver 1.05 V at up to 2 A from a 3 V–17 V input. It implements D-CAP3™ adaptive on-time control, operates at 1.4 MHz nominal switching frequency, and features integrated high-side/low-side MOSFETs in a SOT-563 package. The board supports efficiency measurement, load/line regulation testing, and transient response analysis under real-world DC/DC design conditions.

For engineers reviewing the TPS562242EVM datasheet, TPS562242EVM pinout, TPS562242EVM application, or TPS562242EVM equivalent, this module enables rapid validation of power stage performance-including output ripple (6 mV_PP at 2 A), startup/shutdown timing, Eco-mode light-load behavior, and feedback loop stability-prior to custom PCB design.

Technical Context

The TPS562242EVM implements a fixed-output 1.05 V configuration using R4 = 3.12 kΩ and R5 = 10.0 kΩ feedback resistors, optimized for low-ESR ceramic output capacitors. Its layout places C1/C2/C3 input decoupling capacitors adjacent to the U1 (TPS562242DRLR) SOT-563 IC and uses 2-oz copper on both top and bottom layers for thermal and current handling.

Test points TP2/TP3 monitor VIN/VOUT with dedicated ground references (TP6/TP10), while TP8 provides access to the switch node for ripple and timing analysis. JP1 enables hardware-based EN control, and J1/J2 support 20-AWG wiring for up to 2 A continuous load current with minimal trace loss.

FAQ

What is the purpose of the TPS562242EVM?

The TPS562242EVM is a Texas Instruments evaluation module built around the TPS562242 synchronous buck converter IC. It provides a fully assembled, tested platform to evaluate electrical performance-including efficiency, load/line regulation, startup/shutdown behavior, and output voltage ripple-under defined operating conditions. Engineers use the TPS562242EVM to validate design assumptions before committing to custom power stage layout, reducing risk and time-to-market for 1.05 V/2 A supply rails.

Can the output voltage of the TPS562242EVM be adjusted?

Yes, the TPS562242EVM output voltage is adjustable by modifying the feedback resistor divider network (R4 and R5). The default configuration uses R4 = 3.12 kΩ and R5 = 10.0 kΩ to set 1.05 V, but Equation 1 in the User's Guide allows calculation of new values for outputs from 0.8 V to 10 V. Resistor tolerance should be 1% or better, and values must balance noise immunity against FB input current error to maintain regulation accuracy across the TPS562242EVM's full load range.

What are the key test points on the TPS562242EVM and their functions?

The TPS562242EVM includes dedicated test points for critical signal monitoring: TP2 and TP6 measure VIN and its ground reference; TP3 and TP10 monitor VOUT and its ground reference; TP8 accesses the switch node for ripple and timing analysis; TP9 monitors the EN signal; and TP11 supports loop response measurements. These points are routed with minimal stub length and placed near relevant circuit nodes to preserve signal fidelity during bench characterization of the TPS562242EVM.

How does the TPS562242EVM implement thermal management?

The TPS562242EVM uses 2-oz copper thickness on both top and bottom layers, with the bottom layer serving as a solid ground plane and the top layer containing wide power traces for VIN, VOUT, and GND. The TPS562242DRLR IC in SOT-563 is mounted directly over thermal vias connecting to the internal ground plane, and the 1.2 µH shielded inductor (Wurth 74438357012) is selected for low DC resistance (0.0155 Ω) to minimize heat generation. This layout ensures the TPS562242EVM sustains 2 A continuous output without forced airflow.

Does the TPS562242EVM support Eco-mode operation?

Yes, the TPS562242EVM inherits Eco-mode operation from the underlying TPS562242 IC, which automatically reduces switching frequency under light-load conditions to improve efficiency. This behavior is confirmed in Figure 4-2 of the User's Guide, where efficiency curves at 0.001 A and 0.005 A show higher conversion efficiency at 3 V and 6 V input compared to constant-frequency operation. Eco-mode activation is transparent to the user and requires no configuration on the TPS562242EVM.
