  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
  0.22Ω 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 …
