1.25MHz, 1.5A, MS8 Monolithic Step-Down Converter Keeps Switching Noise above the Signal Spectrum &mdash LT Journal

DESIGN IDEAS 1.25MHz, 1.5A, MS8 Monolithic StepDown Converter Keeps Switching
Noise above the Signal Spectrum
by Karl Edwards
used to further increase the operating frequency to 2MHz, keeping
switching noise out of any particularly sensitive frequency bands. The
high switching frequency reduces the
size of the input and output filtering
components and allows the use of
chip inductors, reducing overall
system cost. The lower storage requirements of these filters make
possible an all-ceramic-capacitor
design.
Inside its MS8 package, the LT1767
provides regulation and control circuitry along with a high efficiency
0.22в„¦ switch. This small-footprint
monolithic approach both reduces
board space and simplifies associated circuitry. Its wide 2.7V to 25V
operating supply range and 1.5A
maximum switching current limit
makes this part ideal in a wide range
of applications. Other useful features
of the LT1767 include an internal
undervoltage lockout and a shutdown …
