Description
XL6009 4A Step-Up Converter with Voltmeter
This adjustable DC-to-DC boost module is designed to raise the input voltage. The listing describes an integrated voltmeter but does not explain its measurement selection or switching method.
Specifications stated in the listing
- Input: 4.3–32V DC
- Adjustable output: 5–39V DC
- Output current: up to 4A; the source says a heatsink is required above 3A
- Efficiency: up to 94%
- Switching frequency: 400kHz
- Output ripple: 50mV (as listed)
- Load regulation: ±0.5%
- Voltage regulation: ±0.5%
- Operating temperature: −40°C to +85°C
- Reverse-input-polarity protection: none
- Short-circuit protection: none
- Thermal shutdown: listed as built in
- Dimensions: approximately 69.8 × 38 mm
As a boost converter, the regulated output must be higher than the input; the listed input and output ranges cannot be combined arbitrarily. The 4A value is a listed maximum, not a guarantee for every voltage or cooling condition. Add a suitable heatsink above 3A and check the actual module’s thermal limits.
Set and measure the output before connecting a load. Check input polarity carefully because reverse-polarity protection is not listed. Do not assume short-circuit protection: the source explicitly says it is not provided. Open the datasheet supplied with the source listing.
