Dual Supercapacitor Backup Power Supply, 0.5V to 5V

Dual Supercapacitor Backup Power Supply, 0.5V to 5V

The LTC3122 is a synchronous step-up DC/DC converter with true output disconnect and inrush current limiting. The 2.5A current limit along with the ability to program output voltages up to 15V makes the LTC3122 well suited for a variety of demanding applications. Once started, operation will continue with inputs down to 500mV, extending runtime in many applications.
