Our Review
The 2pcs XL6009 Boost Buck DC-DC Adjustable Step-UP Down Power Converter Module delivers solid performance for its category. With Type: Step-Down (Buck), Input Voltage: 3-40V, Output Voltage: 3.3V fixed, 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.
The 2pcs XL6009 Boost Buck DC-DC Adjustable Step-UP Down Power Converter Module earns its place in the parts bin. Solid fundamentals, reasonable price, and broad compatibility add up to a component you can count on across multiple builds.
What We Like
- Wide input voltage range accommodates various power sources
- Screw terminals accept a range of wire gauges
- Low quiescent current preserves battery in sleep mode
- High efficiency minimizes heat waste
Watch Out For
- Battery capacity degrades after hundreds of charge cycles
- Output ripple may affect sensitive analog circuits
- Fixed output voltage on some modules limits flexibility
