ETA ETA2843
The ETA2843 is a wide input range, high-efficiency, and high frequency DC-to-DC step-down switching regulator, capable of delivering up to 0.4A of output current. With a fixed switching frequency of 750KHz, this current mode PWM controlled converter allows the use of small external components, such as ceramic input and output caps, as well as small inductors.ETA2843 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. With this OVP function, the IC can stand off input voltage as high as 42V, making it an ideal solution for industrial applications such as smart meters as well as automotive applications.
