Description
XL6009 DC-DC Step-Up Power Converter Module 4A
This DC-DC switching boost converter is capable of driving a 4A load with excellent line and load regulation. The main switching component XL6009 IC is available in fixed output voltages of 3.3 V, 5V, 12V, and an adjustable output version. It is an efficient switching regulator and the output efficiency is significantly higher in comparison with the popular boost regulators. At higher input voltages, the regulator operates at a switching frequency of 400kHz thus allowing the overall board size to be smaller and space-saving.
The XL6009 module is a DC to DC BUCK-BOOST converter module that operates at a switching frequency of 400kHz. In such high frequency, it provides smaller-sized filter components compared with low-frequency switching regulators. It is the upgraded version of the LM2577-based module.

Board Overview
The main driver is XL6009-Adj.
The XL6009-Adj-based DC-DC step-up module offers 4A of rated current from a 3 – 32V of the input voltage. The power module has a potentiometer to adjust the output voltage according to the user needs. Although the module uses a PCB-based heat sink it is recommended to use an additional heat sink if the output power rating exceeds 15W. The module also offers a very high conversion efficiency of less than 94% with a 0.5% load regulation that can be an excellent choice for audio electronics-related products. Higher conversion efficiency enables battery-operated applications as well.
Users can adjust the potentiometer to get the output voltage from 5V to 35V. However, the higher input voltage offers higher load current capabilities.
Interfacing Diagram
The interfacing of the XL6009 module is quite easy. Connect the regulated or unregulated input across the IN+ and IN- pins and use the potentiometer to adjust the output voltage. Connect the load directly at OUT+ and OUT- pins.
