Product Overview

The LTC3122IDE#PBF is a synchronous step-up DC-to-DC Converter with true output disconnect and inrush current limiting. The 2.5A current limit along with the ability to program output voltage 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. It features output disconnect in shutdown, dramatically reducing input power drain and enabling VOUT to completely discharge. Adjustable PWM switching from 100kHz to 3MHz optimizes applications for highest efficiency or smallest solution footprint. The oscillator can also be synchronized to an external clock for noise sensitive applications. Selectable Burst Mode® operation reduces quiescent current to 25µA, ensuring high efficiency across the entire load range. An internal soft-start limits inrush current during start-up. Other features include a <1µA shutdown current and robust protection under short-circuit.
  • Output disconnects from input when shut down
