Bi-Directional Supercap Charger Integrates Backup & Balancing
Linear Technology’s LTC3110 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.
