ETA8121 18V, 2A, Forced PWM Synchronous Step-Down Converter in SOT23-6 DESCRIPTION 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. ETA8121 also employs a forced PWM control scheme, thereby ensuring the minimum ripple voltage. 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. ETA8121 is available in SOT23-6 package.
