A Monolithic Switching Regulator with 100ВµV Output Noise &mdash AN70
PDF, 1.7 Mb, Language: en, File published: Oct 1, 1997
This publication details circuitry and applications considerations for the LT1533 low noise switching regulator. Eleven DC/DC converter circuits are presented, some offering <100µV output noise in a 100MHz bandwidth. Tutorial sections detail low noise DC/DC design, measurement, probing and layout techniques, and magnetics selection.

A Monolithic Switching Regulator with 100ВµV Output Noise
вЂњSilence is the perfectest herald of joy .вЂќ
Jim Williams INTRODUCTION
Size, output flexibility and efficiency advantages have
made switching regulators common in electronic apparatus. The continued emphasis on these attributes has
resulted in circuitry with 95% efficiency that requires
minimal board area. Although these advantages are welcome, they necessitate compromising other parameters. back to the driving source (вЂњreflectedвЂќ noise) and it is
radiated. The multiple transmission paths combine with
the high frequency content to make noise suppression
difficult. Unconscionable amounts of bypass capacitors,
ferrite beads, shields, Mu-metal and aspirin have been
expended in attempts to ameliorate noise-induced effects. Switching Regulator вЂњNoiseвЂќ
Something commonly referred to as вЂњnoiseвЂќ is a primary
concern. The switched mode power delivery that permits
the aforementioned advantages also creates wideband
harmonic energy. This undesirable energy appears as
radiated and conducted components commonly labeled
as вЂњnoise.вЂќ Actually, switching regulator output вЂњnoiseвЂќ is
not really noise at all, but coherent, high frequency residue
directly related to the regulatorвЂ^TMs switching.1 Figure 1
shows typical switching regulator output noise. Two distinct characteristics are present. The slow, ramping output …
