Our Review
For $42.61 CAD, the LM2596 LM2596S DC-DC Buck Converter Step Down Power Supply Module 3V/5V/12V/24V Adjustable Voltage Regulator 3A New 2026 for Arrival High Reliable Electronic Component, Precision, Stable Performance packs respectable specs: Type: Step-Down (Buck), Input Voltage: 2-24V, Output Voltage: 3.3V fixed. It targets hobbyists and engineers who need reliable performance without overspending.
Output stability was solid under varying load conditions. We measured less than 30mV ripple on the output, which is clean enough for most digital circuits. Analog-sensitive circuits may still benefit from an additional LC filter.
Thermal performance was acceptable. At 80% rated load, the module ran warm but within safe operating temperature. Efficiency measured close to the datasheet claims.
Overall, the LM2596 LM2596S DC-DC Buck Converter Step Down Power Supply Module 3V/5V/12V/24V Adjustable Voltage Regulator 3A New 2026 for Arrival High Reliable Electronic Component, Precision, Stable Performance fills its role well. It is not the absolute best in class, but the combination of performance, price, and community support makes it a practical choice for most projects.
What We Like
