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
The quickest way to build an efficient
power system for a battery-powered
portable application is to use an
IC that combines all power control
functions into a single chip, namely a
Power Management Integrated Circuit
(PMIC). PMICs seamlessly manage
power flow from various power sources
(wall adapters, USB and batteries) to
power loads (device systems and the
charging battery), while maintaining
current limits where required (such
as that specified for USB). To this
end, PMICs typically feature built-in
PowerPathв„ў control, DC/DC conver-USB/WALL
