  Introduction
  Linear Technology offers a variety of devices that simplify
  converting power from a USB cable, but the LTCВ®3455
  represents the highest level of functional integration yet
  achieved. The LTC3455 seamlessly manages power flow
  between an AC adapter, USB cable and Li-ion battery,
  while complying with USB power standards, all from a
  4mm Г— 4mm QFN package. In addtion, two high efficiency
  synchronous buck converters generate low voltage rails
  which most USB-powered peripherals require. The
  LTC3455 also provides power-on reset signals for the
  microprocessor, a Hot SwapTM output for powering
  memory cards as well as an uncommitted gain block
  suitable for use as a low-battery comparator or an LDO
  controller. The PCB real estate required for the entire USB
  power control circuit and two DC/DC converters is only
  225mm2.
  The simplified block diagram of the LTC3455 in Figure 1
  shows the major components that allow the LTC3455 to
  accomplish multiple functions. The DC/DC conversion is …

  DESIGN IDEAS Monolithic Synchronous Step-Down
  Regulators Pack 600mA
  Current Rating in a ThinSOT Package
  by Jaime Tseng
  Introduction
  LTCВ®3406, The new
  LTC3406-1.5,
  LTC3406-1.8, LTC3406B, LTC3406B1.5 and LTC3406B-1.8 are the
  industry’s first monolithic synchronous step-down regulators capable of
  supplying 600mA of output current
  in a 1mm profile ThinSOT package.
  These devices are designed to save
  space and increase efficiency for battery-powered portable devices. The
  LTC3406 series uses Burst Mode operation to increase efficiency at light
  loads, consuming only 20ВµA of supply
  current at no load. For noise-sensitive applications, the LTC3406B series
  disables Burst Mode operation and
  operates in pulse skipping mode under light loads. Both consume less
  than 1ВµA quiescent current in shutdown. Space Saving
  Everything about the LTC3406/
  LTC3406B series is designed to make
  power supplies tiny and efficient. An
  entire regulator can fit into a …
