Description
XL6009 4 A Automatic Buck-Boost Voltage Converter
This XL6009-based DC-DC converter can step the output voltage up or down relative to the input. Its output is adjusted using the onboard precision potentiometer. The source specifies integrated MOSFET switching and up to 94% conversion efficiency; actual performance depends on input/output voltage, current, cooling and operating conditions.

Wiring and precautions
Observe input polarity carefully: reverse-polarity protection is not provided. This module also has no short-circuit protection, so use suitable external protection and verify wiring before powering it. Provide adequate cooling; a heatsink is required for output currents above 3 A. Confirm that input voltage, output voltage and current stay within the stated limits. Datasheet
