XL6009 is a high-performance 400KHz 4A switch currency step-up (BOOST) module. This module is coming with the 3rd generation high-frequency switch technology as the core chip, The performance is much higher than LM2577
With 4A high efficiency MOSFET switches, the efficiency of XL6009 can be up to 94%(LM2577current is 3A
With ultra high switch frequency 400KHz , even if small capacity filtering capacitors can achieve very good results, ripple is smaller (Compared to LM2577,its frequency is 50KHz)
With 0.1uF high-frequency bypass capacitor, effectively filter out high-frequency noise
