Power Control Units features: XTW6009 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 ( L* W* H ). 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: 40 C~ + 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 ). 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 ). Color: As Shown. Package Including 1* XL6009 3 32V to 5 35V DC DC Boost Module Output Voltage Adjustable Step up Boost Power Converter Circuit Board Module 400KHz Big Current 4A
