ETA3421 Overview
FEATURES The ETA3421 is a high-efficiency, DC-to-DC step-down constant current LED driver, capable of delivering up to 0.7A of output current. The device operates from an input voltage range of 3.3V to 5.5V and use 0.1V FB voltage to achieve high efficiency. Running at a fixed frequency of 1.5MHz allows the use of small inductance value and low DCR inductors, thereby achieving higher efficiencies.
