  Complete Energy Utilization Improves Run Time of a Supercap
  Ride-Through Application by 40% – 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
  significant amounts of energy, they cannot deliver much
  power due to their significant 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, …
