LTC3124EFE#PBF

LTC3124 is a dual-phase, synchronous step-up DC/DC converter with true output disconnect and inrush current limiting capable of providing output voltages upto 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 upto 15V make the device well suited for a variety of demanding applications. Once started, operation will continue with inputs down to 500mV. This device switching frequency can be programmed from 100KHz to 3MHz to optimize applications for highest efficiency or smallest solution footprint. The oscillator can be synchronized to an external clock for noise sensitive applications. It is widely used in application such as n RF, microwave power amplifiers, piezo actuators, small DC motors, thermal printers, 12V analog rail from battery, 5V, or backup capacitor etc.
