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 …

Introduction
LTCВ®3406, The new
LTC3406-1.5,
LTC3406-1.8, LTC3406B, LTC3406B1.5 and LTC3406B-1.8 are the
industryвЂ™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 …
