XL6019 DC-DC 5A Adjustable Boost Converter Module

Description

The XL6019 DC-DC 5A Adjustable Boost Converter Module is a high-performance step-up power supply designed to efficiently boost a lower input voltage to a higher output voltage. Acting as an upgrade over the older LM2577 and LM2587 modules, the XL6019 operates at a higher switching frequency (220KHz), which translates to higher efficiency, less heat generation, and a more stable output.

Available at Tomson Electronics, this module is an absolute necessity when you need to power 12V or 24V components (like motors, sensors, or LED strips) but only have a lower voltage power source, such as a 3.7V Li-ion battery or a 5V USB power bank. By simply turning the onboard precision blue potentiometer with a flathead screwdriver, you can smoothly dial in your exact required output voltage.

• Solar Power Systems: Boosting varying low-voltage output from small solar panels to a stable charging voltage.

Frequently Asked Questions (FAQ)

Q: Can I use this module to lower my voltage (step-down)?
A: No. The XL6019 is strictly a Boost (step-up) converter. Your output voltage will always be equal to or higher than your input voltage. If you need to reduce voltage, you will need a Buck converter (like an LM2596).

Q: I am turning the potentiometer, but the output voltage isn't changing. Is it broken?
A: Most likely not. These multi-turn potentiometers often require many full rotations (sometimes 10 to 15 full turns counter-clockwise) before the internal wiper reaches a point where it begins altering the voltage. Keep turning it until you see the voltage start to shift on your multimeter.

Q: Does this module need a heatsink?
A: The module can handle low current draws perfectly fine on its own. However, if you are drawing more than ~15W of continuous power (or roughly 2.5A to 3A output), you should attach a small aluminum heatsink to the XL6019 chip to prevent thermal throttling or damage.
