The LM2577 is a DC to DC step-up switching regulator that can provide an adjustable output ranging from +1.25 to 30vdc with a maximum current of 3A. While it is primarily designed to step up +5 to 10vdc to +12vdc at less than 1A, the maximum step-up voltage and current available depend on the input voltage. For instance, with an input voltage of +5vdc, you can expect to get 12vdc output at less than 1A.
This device is well-suited for battery-operated projects that require a regulated power supply, as it boasts a low output ripple thanks to its additional filtering capabilities. It is an adjustable power supply step-up module with a maximum input current of 3A and an impressive conversion efficiency of up to 92%, making it an excellent choice for DIY mobile power or boost charger projects.
