PRODUCT DESCRIPTION: Despite being rated for 4A, I don't recommend these for more than a 3A load, based on experience with about a hundred of them. With ultra high switch frequency 400KHz , even if small capacity filtering capacitors can achieve very good results, ripple is smaller (Compare to LM2577 frequency 50KHz). This module XL6009 is coming with the 3rd generation high-frequency switch technology as the core chip, The performance is much higher than LM2577.
SPECS: • XTW6009 is a high-performance 400KHz 4A switch currency step-up (BOOST) module. • Wide input voltage: 3V~32V; • Optimum operating voltage range: 5~32V;Wide output voltage: 5V~40V; • With 4A high efficiency MOSFET switches, so the efficiency can be up to 94%, (LM2577current is 3A only);
