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.   Refer to the Data below for more information.  Ideal for battery operated projects requiring a regulated power supply.  Has a low output ripple due to extra filtering.
