LM2577 3.0A NPN Output Switch And Operates Across A Wide Input Voltage Range

A boost regulator that produces a higher output voltage than its input, which no linear regulator can do. Used to run 12V equipment from a battery pack, drive LED strings in series, or generate a higher rail from a low voltage source. Requires an external inductor, diode and capacitors. Remember that boosting draws proportionally more input current than it delivers at the output. Produces a higher voltage than the input; 3A internal switch for substantial output power; Wide input voltage range; Fixed and adjustable output versions available
