A 20W, 5V at 4A, step-down regulator can be developed using the LM2577 Simple Switcher IC in a forward converter topology. This design allows the LM2577 IC to be used in step-down voltage applications at output power levels greater than the 1 A LM2575 and 3 A LM2576 buck regulators. In addition, the forward converter can easily provide galvanic isolation between input and output.
