Introduction
Many of todayвЂ™s portable electronic devices require
the ability to operate from a variety of power sources
including USB, wall adapters, and alkaline and lithium
batteries. Designing a power conversion solution that
is compatible with this wide array of power sources can
be daunting. The LTC В®3530 monolithic synchronous
converter simpliп¬Ѓes the task by operating in both buck
and boost modes over an extended input voltage range
of 1.8V to 5.5V. No complicated topology is required to
account for varying inputs that can be above, below or
equal to the output.
The LTC3530 utilizes a proprietary switching algorithm
that provides seamless transitions between buck and
boost modes while simultaneously optimizing efп¬Ѓciency
over all operating conditions. Using this advanced control
algorithm, the LTC3530 is capable of high efп¬Ѓciency, п¬Ѓxed
frequency operation with input voltages that are above,
below, or equal to the output voltage, while requiring only
a single inductor. This capability makes the LTC3530 well …
