    1.25MHz, 1.5A, MS8 Monolithic Step-Down Converter Keeps Switching Noise above the Signal Spectrum
    Docket ↓
    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 ...
