Bidirectional DC/DC Regulator and
Supercapacitor Charger
Design Note 558
Victor Khasiev
Introduction
The LTC В®3110 bidirectional buck-boost DC/DC regulator charges and balances a supercapacitor when a bus
voltage is present (for example 3.3V) and discharges
the supercapacitor into the load when the bus fails.
The LTC3110 maintains the busвЂ™s nominal level (3.3VВ in
the example in Figure 1) even if the supercapacitor
voltage is above or below the nominal bus voltage.
Supporting the load this way allows data backup and
retention during a power interruptionвЂ”important in a
wide variety of industrial and automotive applications. Industrial applications, however, share something
in common with consumer electronics: the trend
toward increased portability and mobility. Space is
increasingly limited for electronics inside modern
industrial equipment. The volume, in particular the
thickness, of a data storage unit is at a premium in
industrial assemblies and modules. With that in mind,
the solution herein aims to minimize the profiles of
the selected components. Table 1 shows two passive
component group options, arranged by thickness: …
