ETA1478
ETA1478 is High Efficiency Synchronous Step-Down Converter manufactured by ETA.
18V, 2A, High Efficiency Synchronous Step-Down Converter in SOT23-6
DESCRIPTION
ETA1478 is a wide input range, high-efficiency and high frequency DC-to-DC step-down switching regulator, capable of delivering up to 2A of output current. With a fixed switching frequency of 500KHz, this current mode PWM controlled converter allows the use of small external ponents, such as ceramic input and output caps, as well as small inductors. ETA1478 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. The IC can stand off input voltage higher than 25V, making it an ideal solution for industrial applications such as LCD TV, Set Top Box, Portable TV, etc.
ETA1478 is available in SOT23-6 package.
