Overview
XR79120
22V, 20A Synchronous Step Down COT Power Module
General 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.
It requires no loop compensation hence simplifying circuit implementation and reducing overall component count.
The control loop also provides 0.
12% load and 0.
17% line regulation and maintains constant operating frequency.
