48V-to-5V DC-DC Converter Using MAX638 Switching Step-Down Regulator Borrows Power from Phone Lines

The telephone subscriber lines provide -48V voltage, but the equipment on the customer premises is usually operated from a lower voltage. The circuit using MAX638 illustrates a conversion of this available voltage to 5V required in modems, telephone test sets, and other portable systems connected
