CAPACITOR SELECTION
A poor choice for an output capacitor can result in poor
efficiency and high output ripple. Ordinary aluminum
electrolytic capacitors, while inexpensive, may have
unacceptably poor ESR and ESL. There are low ESR
aluminum
capacitors
for
switch
mode
DC-DC
converters
which
work
much
better
than
general-purpose components. Tantalum capacitors
provide
still
better
performance
but
are
more
expensive. OS-CON capacitors have extremely low
ESR in a small size. If the capacitance is reduced, the
output ripple will increase.
As most of the input supply is applied across the input
bypass capacitor, the capacitor voltage rating should
be at least 1.25 times greater than the maximum input
voltage.
DIODE SELECTION
Speed, forward drop, and leakage current are three
main considerations in selecting a rectifier diode. The
best performance is obtained with a Schottky rectifier
