XR75100 Overview
The XR75100 is a synchronous step-down controller for point-of load supplies up to 20A. A wide 5.5V to 40V input voltage range allows for single supply operation from industry standard 12V, 18V, and 24V DC and AC rails. With a proprietary emulated current mode Constant On-Time (COT) control scheme, the XR75100 provides extremely fast line and load transient response using ceramic output capacitors.
