QFN-24 Packages n n n The LTC®3110 is a 2A bidirectional buck-boost DC/DC
regulator with capacitor charger and balancer. Its wide
0.1V to 5.5V capacitor/battery voltage and 1.8V to 5.25V
system backup voltage ranges make it well suited to a
wide variety of backup applications using supercapacitors
or batteries. A proprietary low noise switching algorithm
optimizes efficiency with capacitor/battery voltages that
are above, below or equal to the system output voltage. n The LTC3110 can autono...
