Our Review
For $44.43 CAD, the XMKT 5/10pcs DC-DC LM2596 LM2596S-ADJ Step Down Buck Converter 3.2-40V to 1.25-35V Adjustable Power Supply Module Voltage Regulator(5PCS) 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.
Overall, the XMKT 5/10pcs DC-DC LM2596 LM2596S-ADJ Step Down Buck Converter 3.2-40V to 1.25-35V Adjustable Power Supply Module Voltage Regulator(5PCS) 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.
