LM2577 DC-DC Step-Up Power Converter Module
The LM2577 is a DC to DC step-up switching regulator capable of outputting an adjustable voltage ranging from +1.25 to 30VDC, with a maximum current of 3A. Primarily, it is designed to elevate +5 to 10VDC to +12VDC at less than 1A. The output voltage and current are contingent on the input voltage; hence, a higher input voltage will yield a lower output current. For instance, with an input of +5VDC, the output would be 12VDC at less than 1A.
This regulator is perfectly suited for battery-powered projects requiring a regulated power supply. It incorporates additional filtering to minimize output ripple and features an adjustable power supply step-up module. With a maximum input current of 3A and a peak conversion efficiency of 92%, it is highly appropriate for DIY mobile power, boost chargers, and similar applications.
