Overview

ETA3421 0.7A, 1.5MHz Step-Down Constant Current, High Efficiency LED.

Key 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. Other external components, such as ceramic input and output caps, can also be small due to higher switching.
