Our Review
The 1PCS Boost Buck DC-DC Adjustable Step Up Down Converter XL6009 Power Supply Module 20W 5-32V to 1.2-35V (Color : XL6009 with Display) delivers solid performance for its category. With Type: Step-Down (Buck), Input Voltage: 8-40V, 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.
Overall, the 1PCS Boost Buck DC-DC Adjustable Step Up Down Converter XL6009 Power Supply Module 20W 5-32V to 1.2-35V (Color : XL6009 with Display) 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.
