current rating equal to the maximum current limit of the LM2575. The
most stressful condition for this diode is an overload or shorted
output. See Table 1.
B. The reverse voltage rating of the diode should be at least 1.25
times the maximum input voltage.

ground pins provides sufficient bypassing.
To further simplify the buck regulator design procedure, TI is making available computer design software to be
used with the Simple Switcher line of switching regulators. Switchers Made Simple (version 3.3) is available on
a (3½″) diskette for IBM compatible computers from a TI sales office in your area.
