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

DESCRIPTION

FEATURES

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

0.15V feedback voltage, which minimize the power loss on

the sense resistor in a LED driver system. With a fixed

switching frequency of 600KHz, This current mode PWM

controlled LED Driver allows the use of small external

components, such as ceramic input and output caps, as

well as small inductors. ETA2840 also employs a

proprietary control scheme that switches the device into a

power save mode during light load, thereby extending the

range of high efficiency operation. An OVP function

protects the IC itself and its downstream system against

input voltage surges. With the hysteresis, EN can be

controlled by the ambient light-sensitive resistor.

ETA2840 is available in a space-saving SOT23-6 package.
