XL6019 5A DC-DC Adjustable Boost Module

Step up a lower DC voltage to the level your project actually needs with this XL6019 5A Boost Power Module, an upgraded step-up converter that outperforms older XL6009-based boards in both current handling and thermal stability. Built around the XLSEMI XL6019 IC with an integrated N-channel power MOSFET, this module efficiently converts a lower input voltage into a stable, higher output voltage, making it a practical building block for a wide range of battery-powered and bench power projects.

A multi-turn precision potentiometer lets you fine-tune the output voltage with more accuracy than the single-turn trimpots found on cheaper boost modules, so you can dial in exactly the voltage your circuit requires. The module supports a wide input range and can deliver up to 5A of output current in short bursts, with sustained current handling recommended around 3A unless a heatsink is added. Built-in over-temperature and over-current protection help safeguard both the module and your connected load from damage during extended or high-current use.

This boost converter is a versatile addition to any hobbyist’s bench, commonly used to power 5V USB devices from a 3.7V lithium cell, step up battery voltage for LED strips and driver circuits, or supply higher voltage rails for motors and other demanding electronics from a lower-voltage source. It’s a reliable, high-efficiency choice for robotics, automotive electronics, solar setups, and general DIY power supply projects.
