  High Voltage, Low Noise, DC/DC Converters &mdash AN118
  PDF, 2.6 Мб, Файл опубликован: 28 мар 2008
  Photomultipliers (PMT), avalanche photodiodes (APD), ultrasonic transducers, capacitance microphones, radiation detectors and similar devices require high voltage, low current bias. Additionally, the high voltage must be pristinely free of noise; well under a millivolt is a common requirement with a few hundred microvolts sometimes necessary. Normally, switching regulator configurations cannot achieve this performance level without employing special techniques. One aid to achieving low noise is that load currents rarely exceed 5mA. This freedom permits output filtering methods that are usually impractical.

  High Voltage, Low Noise, DC/DC Converters
  A Kilovolt with 100 Microvolts of Noise
  Jim Williams This publication describes a variety of circuits featuring
  outputs from 200V to 1000V with output noise below 100ВµV
  measured in a 100MHz bandwidth. Special techniques
  enable this performance, most notably power stages
  optimized to minimize high frequency harmonic content.
  Although sophisticated, all examples presented utilize
  standard, commercially available magnetics—no custom
  components are required. This provision is intended to
  assist the user in quickly arriving at a produceable design.
  Circuits and their descriptions are presented beginning
  with the next ink.

  Designs From a Once Lazy Sabbatical
  Jim Williams
  Introduction
  Linear Technology has a sabbatical program. Every five
  years employees are granted sabbatical leave, which may
  last up to six weeks. You have 18 months from each five
  year employment anniversary to take the leave. Sabbatical
  is fully company paid and has no restrictions. The time is
  yours to do with as you please.
  People exercise all degrees of freedom with their sabbaticals. They go sailing, they go to South Sea islands, they ski
  some mountain nobody ever heard of, they trek in Nepal.
  Houses get fixed, cars restored and children played with.
  For my third sabbatical I resolved to do absolutely nothing.
  For the first time in my life I was really tired, and I knew it.
  A six week rest sounded just fine. I’d walk the dog and
  spend time with my wife and son. That’s it. No transistors,
  no resistors, no op amps and, above all, no writing. I was
  so written out the thought of picking up a pencil produced
  an instant headache. …

  advertisement LT1534 Ultralow Noise Switching Regulator Controls EMI
  Design Note 178
  Jeff Witt
  Today’s circuit designer is often challenged to assemble a high performance system by combining
  sensitive analog electronics with potentially noisy DC/
  DC converters. Requirements for a small, efficient,
  cost effective solution are in conflict with acceptable
  noise performance—noisy switching regulators call for
  п¬Ѓltering, shielding and layout revisions that add bulk
  and expense. Most electromagnetic interference (EMI)
  problems associated with DC/DC converters are due to
  high speed switching of large currents and voltages. To
  maintain high efficiency, these switch transitions are
  designed to occur as quickly as possible. The result is
  input and output ripple that contains very high harmonics of the switching frequency. These fast edges also
  couple through stray magnetic and electric п¬Ѓelds to
  nearby signal lines, making efforts to п¬Ѓlter the supply
  lines ineffective.
  The LTВ®1534 ultralow noise switching regulator provides
  an effective and flexible solution to this problem. Using two external resistors, the user can program the
  slew rates of the current through the internal 2A power
  switch and the voltage on it. Noise performance can
  be evaluated and improved with the circuit operating …
