XL6019 DC-DC 5A Adjustable Boost Power Supply Module(RED) DC to DC step up module based on the upgraded XL-Semi XL-6019, offering up to 5A switching current and conversion efficiency of up to 97%. This XL6019 boost converter has two input pins for VCC and GND on the left side of the module. It has two output pins on the right side of the module. To get the desired output voltage you have to rotate the trimpot screw. It changes the feedback resistance value and thus the output voltage with respect to the input voltage. As this module is a step-up converter, therefore, the output current is always smaller than the input current. If the output power is greater than 10W then add the heat sink with the module otherwise it may damage the module.  Features With reverse connect protection, output 5V / 12V / 24V adjustable, beyond LM2577 performance. The built-in thermal protection, over-current protection reliability. Wide input voltage range, the input voltage up to 35V. Adjustable output voltage, maximum support 40V. The built-in thermal protection, over-current protection full reliability protection circuit, high reliability. System conversion efficiency can achieve 90% above, convenient thermal design. TO263-5 l standard packaging, suitable for booster application within 30W. Also check the LM2596 Mini 360 Aircraft Power Supply Step-down Module. It is a non-isolated BUCK module with synchronous rectification. The module features an integrally molded power inductor and a synchronous rectifier control chip.
