General Description

The LTC®3122 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.
