  Switching Regulator Circuit Collection &mdash AN30
  PDF, 606 Kb, Datei veröffentlicht: Feb 1, 1989
  Switching regulators are of universal interest. Linear Technology has made a major effort to address this topic. A catalog of circuits has been compiled so that a design engineer can swiftly determine which converter type is best. This catalog serves as a visual index to be browsed through for a specific or general interest.

  Switching Regulator Circuit Collection
  John Seago
  Switching regulators are of universal interest. Linear
  Technology has made a major effort to address this topic.
  A catalog of circuits has been compiled so that a design
  engineer can swiftly determine which converter type is
  best. This catalog serves as a visual index to be browsed
  through for a specific or general interest. The catalog is organized so that converter topologies can
  be easily found. There are 12 basic circuit categories:
  Battery, Boost, Buck, Buck-Boost, Flyback, Forward, High
  Voltage, Multioutput, Off Line, Preregulator, Switched
  Capacitor and Telecom. Additional circuit information can
  be located in the references listed in the index. The
  reference works as follows, i.e., AN8, Page 2 = Application
  Note 8, Page 2; LTC1044 DS = LTC1044 data sheet;
  DN17 = Design Note 17. DRAWING INDEX

  New Developments in RS232 Interfaces
  Design Note 4
  Robert Dobkin
  New RS232 interface chips have been developed that
  offer significant advantages over older devices such
  as the 1488 and 1489. The new RS232 interface ICs
  improve speed, power, voltage supply requirements, and
  protection over older devices. Further, the new chips
  are easier to use, requiring fewer external components
  and may be turned off to a “zero” power supply current
  condition for use in battery powered systems.
  The new RS232 drivers are implemented in a monolithic
  bipolar technology. A unique output stage was designed
  that provides large output swings, minimizing power
  supply voltage requirements, while retaining outstanding overload protection features. The outputs can be
  driven beyond the power supply voltage without drawing excessive current or forcing current back into the
  power supplies. Of course, current limiting is included
  to protect against short circuit conditions.
  Initial consideration of technologies for implementing
  RS232 interfacing might include CMOS as a possible
  technology for this type of application. Power supply
  requirements are low, output voltage swing is high,
  and higher voltage CMOS technologies are available …
