Complete Energy Utilization Improves Run Time of a Supercap
Ride-Through Application by 40% вЂ“ Design Note 485
George H. Barbehenn
Introduction
Many electronic systems require a local power source that
allows them to ride through brief main power interruptions without shutting down. Some local power sources
must be available to carry out a controlled shutdown if
the main power input is abruptly removed. Complete Energy Utilization Maximizes Run Time
of Supercap Ride-Through Application
Figure 1 shows a complete 3.3V/200mA ride-through application that maximizes the amount of power extracted
from the supercap to support the load. A battery backup can supply power in the event of a
mains shutdown, but batteries are not well suited to
this particular application. Although batteries can store
signiп¬Ѓcant amounts of energy, they cannot deliver much
power due to their signiп¬Ѓcant source impedance. Also,
batteries have п¬Ѓnite lives of ~2 to 3 years, and the maintenance required for rechargeable batteries is substantial. The LTC В®4425 complete 2A supercapacitor charger. It
clamps the individual cell voltages to ensure that the
cells do not overvoltage during charging and balances
the cells throughout charge and discharge. The main components of the ride-through application
include: The LTC3606 micropower buck regulator produces
the regulated 3.3V output. Supercapacitors are well suited to such ride-through
applications. Their low source impedance allows them
to supply signiп¬Ѓcant power for a relatively short time, …
