ETA2840

42V Input Standoff Voltage, 1A Step-Down LED Driver in SOT23-6

The ETA2840 is a wide input range, high-efficiency, and high frequency DC-to-DC step-down LED driver, capable of delivering up to 1.5A of output current. ETA2840 provide 0.16V feedback voltage, which minimize the power loss on the sense resistor in a LED driver system.
