Chargeur USB 5V pour batteries 18650 – Test et Avis

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

Wide input voltage: 3V~32V;Optimum operating voltage range: 5~32V;Wide output voltage: 5V~35V

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
