The XL6009 is a 4A switching current boost (BOOST) module. The module uses high-frequency switching technology XL6009E1 as the core chip, the performance is superior to LM2577. The XL6009 boost module is less expensive and performs better, and the LM2577 module is about to be phased out. Ultra-wide input voltage 3V~32V, zui good working voltage range is 5~32V; Ultra-wide output voltage 5V~35V; Built-in 4A high efficiency MOSFET switch tube, the efficiency is up to 94%; (LM2577 current is only 3A) The switching frequency is 400KHz, which can achieve very good results with a small-capacity filter capacitor. The ripple is smaller and the volume is smaller. (LM2577 frequency is only 50KHz) Technical Parameters: Model specificationXL6009 boost module Modular natureNon-isolated boost (BOOST) Rectification methodAsynchronous rectifier Input range3V~32V Output range5V~35V Input Current4A (maximum ), no load 18mA (5V input, 8V output,no load less than 18mA.
