Our Review
The LM2596 DC-DC Buck Converter Voltage Regulator Adjustable DC to DC 4.0-40V to 1.25-37V 2A Power Supply Module with LED Voltmeter Display (8PCS) delivers solid performance for its category. With Type: Step-Down (Buck), Input Voltage: 2-24V, Output Voltage: 1.25-35V 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 LM2596 DC-DC Buck Converter Voltage Regulator Adjustable DC to DC 4.0-40V to 1.25-37V 2A Power Supply Module with LED Voltmeter Display (8PCS) delivers what you need without unnecessary complexity. Recommended for hobbyists and engineers working on projects where power & batteries components are essential.
What We Like
- Stable output voltage under varying load conditions
- Built-in protection circuits prevent damage
- Low quiescent current preserves battery in sleep mode
- Screw terminals accept a range of wire gauges
Watch Out For
- Thermal shutdown possible in poorly ventilated enclosures
- Efficiency drops at very light loads
- No reverse polarity protection on input
