ETA ETA1478
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 components, such as ceramic input and output caps, as well as small inductors. 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.| Part No. | ETA1478 |
