Product Description
The LM2577 is a DC to DC step-up switching regulator that can output an adjustable voltage from +1.25 to 30vdc, with a maximum current of 3A. However, it is mainly designed to step up +5 to 10vdc to +12vdc at less than 1A. The output voltage and current depend on the input voltage, so a higher input voltage will result in a lower output current. For example, if you input +5vdc, you can expect to get 12vdc output at less than 1A.
This regulator is ideal for battery-operated projects that need a regulated power supply. It has extra filtering to reduce the output ripple. It also has an adjustable power supply step-up module, with a maximum input current of 3A and a highest conversion efficiency of 92%. It is very suitable for DIY mobile power, boost charger and other applications.
