Description

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:

1. Wide Input voltage: 3.5V-35V
2. Output Voltage: 4-35V (Adjustable)
3. Output current: rated current 3A MAX ( Heat-sink Needed)
4. Conversion efficiency: Up to 92% (output voltage higher, the higher the efficiency)
5. Switching Frequency: 50KHz
6. Rectifier: Non-Synchronous Rectification
7. Short circuit protection: current limiting, since the recovery
8. High-quality PCB FR4 Grade with FPT Certified

Package Includes:

1 x LM2577 DC-DC Step-Up Power Converter Module
