Our Review
After integrating the 10 pcs LM2596HVS LM2596 HV LM2596HV DC-DC Adjustable Step Down Buck Converter Power Module 4.5-50V to 3-35V Urrent limiting into several test builds, we found it to be a capable component for the price. Key specs include Type: Step-Down (Buck), Input Voltage: 4.5-28V, Output Voltage: 3.3V fixed.
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 10 pcs LM2596HVS LM2596 HV LM2596HV DC-DC Adjustable Step Down Buck Converter Power Module 4.5-50V to 3-35V Urrent limiting 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
- LED indicators show power and charging status
- Built-in protection circuits prevent damage
- Stable output voltage under varying load conditions
- High efficiency minimizes heat waste
Watch Out For
- No reverse polarity protection on input
- Thermal shutdown possible in poorly ventilated enclosures
- Electrolytic capacitors age and degrade over years
