商品介紹
一、DESCRIPTION
XR8121 isa 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. XR8121 also employs a
forced PWM control scheme, thereby ensuring the minimum ripple voltage. Its input can withstand a voltage surge as high as 30V, making it an ideal solution for industrial applications
such as Surveillance Camera, LCD TV, Set Top Box, etc.
XR8121 is available in SOT23-6 package
