Our Review

For $43.68 CAD, the 10 PCS LM2596 DC to DC Buck Converter 3.0-40V to 1.5-35V Power Supply Step Down Module (10X) packs respectable specs: Type: Step-Down (Buck), Input Voltage: 8-40V, Output Voltage: 1.25-26V adjustable. 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.

For the price point, the 10 PCS LM2596 DC to DC Buck Converter 3.0-40V to 1.5-35V Power Supply Step Down Module (10X) delivers what you need without unnecessary complexity. Recommended for hobbyists and engineers working on projects where power & batteries components are essential.
