DescriptionXTW6009 is a high-performance 400KHz 4A switch currency step-up (BOOST) module. This module XL6009 is coming with the 3rd generation high-frequency switch technology as the core chip, The performance is much higher than LM2577.Features- Color: Shown in the pictures. - Material: Electric components. - Size: Approx. 4.4 * 2.2 * 1.3cm/ 1.7 * 0.87 * 0.5 inch (LWH). - Input Range: 3V ~ 32V. - Output Range: 5V ~ 35V. - Input Current: 4A (max). - Switching frequency: 400KHz. - Load Regulation: +/-0.5%. - Voltage Regulation: +/-0.5%. - Operating Temperature: -40C ~ +85 C. - Input way: IN+, IN-. - Output way: OUT+, OUT-. - With 4A high efficiency MOSFET switches, so the efficiency can be up to 94%, (LM2577current is 3A only). - 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).
