Dual Supercapacitor Backup Power Supply, 0.5V to 5.4V

The LTC3124 is a dual-phase, synchronous step-up DC/DC converter with true output disconnect and inrush current limiting capable of providing output voltages up to 15V. Dual-phase operation significantly reduces peak inductor and capacitor ripple currents, minimizing inductor and capacitor size. The 2.5A per phase current limit, along with the ability to program output voltages up to 15V make the LTC3124 well suited for a variety of demanding applications. Once started, operation will continue with inputs down to 500mV.
