Overview

The LTC7124 is a dual channel, 3.5A per output, high efficiency monolithic step-down regulator capable of operating from input supplies up to 17V. The programmable switching frequency ranges from 500kHz to 4MHz with a ±25% external clock synchronization capability around the programmed frequency. The regulator features ultralow quiescent current for high efficiency over a wide VOUT range. The step-down regulator operates from an input voltage range of 3.1V to 17V and provides an adjustable output range from 0.6 to 99% of VIN while delivering up to 3.5A of output current per channel. A user selectable mode input is provided to allow the user to trade off output ripple for light load efficiency; Burst Mode operation provides the highest efficiency at light loads, while forced continuous operation provides the lowest output ripple. The LTC7124 includes spread spectrum modulation for low radiated and conductive noise. The LTC7124 is offered in a thermally enhanced, low profile 24-lead 3mm × 5mm QFN package.
