LTC3124 - 5A 2-Phase Synchronous Step-Up DC/DC Converter

General Description

The LTC®3124 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.

Key Features
