Seamless, Automatic Transition Between Two Input Power
Sources and Meets Stringent CISPR 25 Class 5 EMI Limits
John Canfield Many electronic devices must seamlessly transition
between a wide variety of input power sourcesвЂ”such as
batteries, automotive rails, wall adapters and USB ports.
Traditionally, power supply designers rely on Schottky
diodes or a prioritized PowerPath (IC controlled MOSFET
switches) to combine input sources. Since both methods
require additional components in front of the switching
power supply, solution size and design complexity increase
while overall supply efficiency is reduced. With its ability to
operate directly from two different input power sources,
the LTC3126 eliminates these disadvantages and enables
smaller and higher efficiency multisource power supplies.
45 (FM) 40
PEAK RADIATED EMI (dBВµV/m) The LTC3126 operates directly from two
independent power sources, drastically
simplifying the design of such systems
by minimizing component count and
solution size, as shown in FigureВ 1,
while maintaining high overall system
efficiency. Ease of use is enhanced by …
