18V Buck-Boost Converter with Intelligent PowerPath
Control Delivers >2A at 95% Efficiency from Dual Inputs
Eddy Wells The requirement to operate from multiple input sources is
increasingly common for applications powered from various
battery chemistries, wall adapters and DC voltage rails
such as USB. The ability to provide step-up or step-down
conversion is often necessary, depending on the voltage
range of each input and the desired output voltage.
While powering from multiple sources
is conceptually straightforward, implementation can be complicated. Losses
in the power path, prioritization of the
input sources and voltage spikes resulting
from inductive cable insertion can all
add cost and complexity to the system. with the ability to deliver over 2A current
to the load. The LTC3118вЂ™s current mode
control architecture responds rapidly to
line or load transients, maintaining tight
regulation of the output. For battery
powered applications, extended run times
are achieved with Burst ModeВ® operation. The LTC3118 addresses these issues by
combining a dual, low loss PowerPath
controller with a high efficiency buckboost converter, as shown in Figure 1. The
unique architecture allows conversion …
