LM2577 DC to DC step-up switching regulator, adjustable 1.25 to 30vdc output, up to 3A. The LM2577 is really designed to step up 5 to 10vdc to 12vdc at < 1A. The maximum step-up voltage and current available depends on the input voltage, so if you input 5vdc you could expect to get 12vdc output at < 1A. Ideal for battery-operated projects requiring a regulated power supply. It has a low output ripple due to extra filtering. It has an adjustable Power Supply Step-up Module, maximum input current 3A, the highest conversion efficiency 92%. It very suitable for DIY a mobile power, Boost charger. Features: Wide Input voltage: 3.5V-35V Output Voltage: 4-35V (Adjustable) Output current: rated current 3A MAX ( Heat-sink Needed) Conversion efficiency: Up to 92% (output voltage higher, the higher the efficiency) Switching Frequency: 50KHz Rectifier: Non-Synchronous Rectification Short circuit protection: current limiting, since the recovery High-quality PCB FR4 Grade with FPT Certified. Specifications: Wide Input voltage 3.5V-35V Output Voltage 4-35V Output current Rated current 3A MAX Conversion efficiency Up to 92% Switching Frequency 50KHz Operating temperature -40 to 85 C Load regulation ± 0.5% Voltage regulation ± 0.5% Length 52mm Width 22mm Height 20mm Weight 13 gm Package Includes: 1 x LM2577 DC-DC Step-Up Power Converter Module. *Product Images are shown for illustrative purposes only and may differ from actual product.
