LTC7124EUDD描述

The LTC7124EUDD 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
aroundtheprogrammedfrequency. The regulatorfeatures
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 0.6V to 99% of VIN while delivering up to 3.5A
ofoutput currentper channel. A user selectablemode 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
