ETA ETA8121
ETA8121 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 1MHz, 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. Its input can withstand a voltage surge as high as 24V, making it an ideal solution for industrial applications such as Surveillance Camera, LCD TV, Set Top Box, etc.| Part No. | ETA8121 |
