  DESIGN FEATURES SOT-23 Switching Regulators Deliver
  Low Noise Outputs in a Small Footprint
  by Steve Pietkiewicz
  Introduction L1
  4.7ВµH 100 90
  EFFICIENCY (%) As portable electronics designers continue to press for reduction in
  component sizes, Linear Technology
  introduces the LT1611 and LT1613
  SOT-23 switching regulators. These
  current mode, constant frequency
  devices contain internal 36V switches
  capable of generating output power
  in the range of 400mW to 2W, in a 5lead SOT-23 package. The LT1613
  has a standard positive feedback pin
  and is designed to regulate positive
  voltages. The LT1611 has a novel
  feedback scheme designed to directly
  regulate negative output voltages
  without the use of level-shifting circuitry. Boost, single-ended primary
  inductance converters (SEPIC) and
  inverting configurations are possible
  with the LT1613 and LT1611. The
  high voltage switch allows hard-todo, yet popular DC/DC converter …

  DESIGN FEATURES Micropower 5-Lead SOT-23
  Switching Regulators Extend Battery
  Life in Space-Sensitive Applications
  by Bryan Legates
  Introduction L1
  4.7ВµH VIN
  1.5V TO 3V The LT1615 and LT1617 are pin
  compatible with two other members
  of the PowerSOTв„ў family, the LT1613
  and LT1611, respectively. This allows
  the same board layout to be used to
  evaluate the performance of multiple
  devices. The LT1613 and LT1611 are
  both current mode, constant frequency devices, capable of producing
  larger output currents than the
  LT1615 and LT1617.1 LT1615 2-Cell to 3.3V
  Boost Converter
  A popular supply for many portable
  electronic devices, a 2-cell alkaline to
  3.3V converter with the LT1615 can
  deliver 60mA of load current. The
  circuit is shown in Figure 1 and the
  system efficiency appears in Figure 2. …

  DESIGN FEATURES Inverting Switching Regulator Delivers
  High Current/Low Noise Outputs
  in a SOT-23
  by Albert Wu
  Introduction
  The LT1931 is the industry’s highest
  power SOT-23 inverting switching
  regulator. The on-chip 1A switch
  allows high output currents to be
  generated. In a typical 5V to –5V
  application, the part can deliver
  350mA; a 5V to –12V application can
  provide 150mA. The LT1931 switches
  at a fixed frequency of 1.2MHz, allowing the use of tiny, low cost capacitors
  and inductors of 2mm or less in height.
  The constant switching frequency
  keeps the output voltage noise low
  and predictable, making designs with
  output voltage ripple less than 5mVP-P
  easily achievable. An integrated shutdown feature limits the supply current
  to less then 1ВµA when the part is
  disabled, extending battery life. The
  high power and low noise LT1931 …
