Minimizing Switching Regulator Residue in Linear Regulator Outputs &mdash AN101
PDF, 358 Kb, 语言: en, 档案已发布: Jul 16, 2005, 页数: 12
Application Note 101. Linear regulators are commonly employed to post-regulate switching regulator outputs. Benefits include improved stability, accuracy, transient response and lowered output impedance. Ideally, these performance gains would be accompanied by markedly reduced switching regulator generated ripple and spikes. In practice, all linear regulators encounter some difficulty with ripple and spikes, particularly as frequency rises. This publication explains the causes of linear regulators' dynamic limitations and presents board level techniques for improving ripple and spike rejection. A hardware based ripple/spike simulator is presented, enabling rapid breadboard testing under various conditions. Three appendices review ferrite beads, inductor based filters and probing practice for wideband, sub-millivolt signals.

Minimizing Switching Regulator Residue
in Linear Regulator Outputs
Banishing Those Accursed Spikes
Jim Williams
INTRODUCTION
Linear regulators are commonly employed to post-regulate
switching regulator outputs. Beneﬁts include improved
stability, accuracy, transient response and lowered output
impedance. Ideally, these performance gains would be
accompanied by markedly reduced switching regulator
generated ripple and spikes. In practice, all linear regulators
encounter some difﬁculty with ripple and spikes, particularly as frequency rises. This effect is magniﬁed at small
regulator VIN to VOUT differential voltages; unfortunate,
because such small differentials are desirable to maintain
efﬁciency. Figure 1 shows a conceptual linear regulator
and associated components driven from a switching
regulator output.
The input ﬁlter capacitor is intended to smooth the ripple and
spikes before they reach the regulator. The output capacitor maintains low output impedance at higher frequencies,
improves load transient response and supplies frequency
compensation for some regulators. Ancillary purposes include noise reduction and minimization of residual inputderived artifacts appearing at the regulators output. It is …

Rail-to-Rail I/O and 2.4V Operation Allow UltraFast Comparators to be Used on Low Voltage Supplies
Design Note 248
Glen Brisebois
The new LTВ®1711 to LT1714 family of UltraFastв„ў
comparators have full differential rail-to-rail inputs and
outputs and operate down to 2.4V, allowing unfettered
application on low supply voltages. The LT1711 (single)
and LT1712 (dual) are speciп¬Ѓed at 4.5ns of propagation
delay and 100MHz toggle frequency. The lower power
LT1713 (single) and LT1714 (dual) are speciп¬Ѓed at 7ns
of propagation delay and 65MHz toggle frequency. All
of these comparators are fully equipped to support
multiple supply applications and have Latch Enable
(LE) pins and complementary outputs like the popular
LT1016, LT1116, LT1671 and LT1394. They are available in MSOP and SSOP packages, fully speciп¬Ѓed
over commercial and industrial temperature ranges
on 2.7V, 5V and В±5V supplies.
Simultaneous Full Duplex 75Mbaud Interface
with Only Two Wires
The circuit of Figure 1 shows a simple, fully bidirectional, differential 2-wire interface that gives good
results to 75Mbaud, using the lower power LT1714.
Eye diagrams under conditions of unidirectional and
bidirectional communication are shown in Figures 2 …

DESIGN FEATURES New UltraFast Comparators: Rail-toRail Inputs and 2.4V Operation Allow
Use on Low Supplies
by Glen Brisebois
Introduction
The new LT1711 family of UltraFast
comparators has fully differential railto-rail inputs and outputs and
operates on supplies as low as 2.4V,
allowing unfettered application on low
voltages. The LT1711 (single) and
LT1712 (dual) are specified at 4.5ns
of propagation delay and 100MHz
toggle frequency. The low power
LT1713 (single) and LT1714 (dual)
are specified at 7ns of propagation
delay and 65MHz toggle frequency.
All of these comparators are fully
equipped to support multiple-supply
applications, and have latch-enable
pins and complementary outputs like
the popular LT1016, LT1671 and
LT1394. They are available in MSOP
and SSOP packages, fully specified
over commercial and industrial temperature ranges on 2.7V, 5V and В±5V …
