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 specification：XL6009 boost module Modular nature：Non-isolated boost (BOOST) Rectification method：Asynchronous rectifier Input range：3V~32V Output range：5V~35V Input Current：4A (maximum ), no load 18mA (5V input, 8V output,no load less than 18mA. The higher the voltage, the greater the no-load current.) Conversion efficiency：<94%(the greater the pressure difference,the lower the efficiency) On-off level：400KHz Output ripple：50mV(the higher the voltage,the larger the current,the larger the ripple) Hello Elena：±0.5% Voltage regulation：±0.5% Operating temperature：-40°C~ +85°C Dimensions 43mm * 21mm (L*W) IN+ input positive IN- input negative OUT+ output positive OUT-output negative!
