XR79120：22V, 20A Synchronous Step Down Constant On-Time QFN Module
The XR79120 is a synchronous step-down controller for point-of load supplies up to 20A. 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 exceptional load and line regulation and maintains constant operating frequency. A selectable power saving mode allows the user to operate in discontinuous mode (DCM) at light current loads thereby significantly increasing the converter efficiency.
A host of protection features, including over-current, over-temperature, short-circuit and UVLO, help achieve safe operation under abnormal operating conditions.
The XR79120 is available in RoHS compliant, green/halogen free space saving 12x14x4mm QFN package.
