Our Review
The 5 Pack LM2596 LM2596S DC-DC Step-Down Adjustable Voltage Regulator, Input 3.0-40V, Output 1.25-35V, Variable Buck Converter Power Supply Module delivers solid performance for its category. With Type: Step-Down (Buck), Input Voltage: 2-24V, Output Voltage: 1.25-26V adjustable, it covers the essentials that most makers and engineers need for their projects.
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.
For the price point, the 5 Pack LM2596 LM2596S DC-DC Step-Down Adjustable Voltage Regulator, Input 3.0-40V, Output 1.25-35V, Variable Buck Converter Power Supply Module delivers what you need without unnecessary complexity. Recommended for hobbyists and engineers working on projects where power & batteries components are essential.
