DESCRIPTION
The XR79106 has a load current rating of 6A. 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 XR79106 provides extremely fast line and load transient response using ceramic output capacitors. It requires no loop compensation, simplifying circuit implementation and reducing overall component count. The control loop also provides 0.2% load and 0.2% line regulation and maintains constant operating frequency. A selectable power saving mode allows the user to operate in Discontinuous Current Mode (DCM) at light current loads, significantly increasing the converter efficiency. A host of protection features, including overcurrent, over temperature, short-circuit and UVLO, helps achieve safe operation under abnormal operating conditions. The XR79106 is available in a RoHS-compliant, green / halogen-free space-saving 8mm x 8mm x 4mm GQFN package.
