XR79120 Description
The XR79120 is a 20A synchronous step-down Power Module for point-of load supplies. A wide 4.5V to 22V input voltage range allows for single supply operation from industry standard 5V, 12V, and 19.6V rails. With a proprietary emulated current mode Constant On-Time (COT) control scheme, the XR79120 provides extremely fast line and load transient response using ceramic output capacitors.
