Product details
Overview
TPS62040EVM-229 from Texas Instruments is an evaluation module designed to characterize the TPS62040 adjustable high-efficiency step-down DC-DC converter, supporting 2.5 V–6 V input, 0.7 V–6 V output (factory-set to 1.8 V), and up to 1.2 A load current in PWM or PFM/PWM mode.
For engineers reviewing the TPS62040EVM-229 datasheet, TPS62040EVM-229 pinout, TPS62040EVM-229 application, or TPS62040EVM-229 equivalent, this EVM enables rapid validation of voltage regulation performance, efficiency vs. load, transient response, and mode-switching behavior under real-world lab conditions with minimal setup.
Technical Context
The TPS62040EVM-229 implements a synchronous buck topology using the TPS62040DGQ IC in a DGS10 (3 mm × 3 mm, 10-pin VSSOP) package. It supports dual operating modes via JP2: fixed-frequency PWM for low-noise applications and PFM/PWM hybrid mode for ultra-low quiescent current at light loads.
Input power is applied via J1 (VIN/GND), output is accessed via J3 (VOUT/GND), and feedback is configured by R1/R2 resistor divider per the adjustable output design. The board integrates 6.2 µH power inductor L1 and dual 22 µF ceramic output capacitors (C3/C4) optimized for stability and ripple suppression across 100 kHz–2 MHz switching.

FAQ
What is the primary function of the TPS62040EVM-229?
The TPS62040EVM-229 is a dedicated evaluation module for the TPS62040 adjustable synchronous buck converter. It provides a fully assembled, tested platform to measure efficiency, transient response, mode-switching behavior, and thermal performance without custom PCB design. Engineers use the TPS62040EVM-229 to validate system-level power architecture before committing to production layout.
Can the output voltage of the TPS62040EVM-229 be changed from its factory setting?
Yes, the TPS62040EVM-229 is configured as an adjustable-output module with default 1.8 V set by R1 and R2. Users can reconfigure the output voltage between 0.7 V and 6 V by replacing either resistor per the TPS62040 datasheet's feedback divider equations. The board includes solder pads and routing compatible with standard 0805/0603 resistors for quick iteration.
How do I switch between PWM and PFM/PWM modes on the TPS62040EVM-229?
Mode selection is controlled by JP2: placing the shunt across "FIXED FREQ" forces continuous PWM operation for consistent switching frequency and lower output noise; placing it across "PWR SAVE" enables automatic PFM/PWM transition, reducing quiescent current and switching frequency at light loads to maximize efficiency across the full 0–1.2 A range. No firmware or external control signals are required.
Does the TPS62040EVM-229 include input and output test points?
Yes, the TPS62040EVM-229 features dedicated VIN and VOUT test points adjacent to J1 and J3 headers, respectively. These allow direct oscilloscope or multimeter probing without wire leads or soldering, minimizing measurement error from trace resistance and inductance. Ground test points are also provided near each power terminal for accurate differential measurements.
Is the TPS62040EVM-229 compliant with FCC or CE emissions standards?
No - the TPS62040EVM-229 is explicitly designated for engineering development and laboratory evaluation only. As stated in the EVM User's Guide (SLVU089), it lacks shielding, filtering, and enclosure design required for regulatory compliance. Users must integrate final power stages into certified end-equipment and perform full EMC testing per applicable standards.
