Exar Corporation XRP6141
The XRP6141 is a synchronous step-down controller for point-of load supplies up to 35A. With a proprietary emulated current mode Constant On-Time (COT) control scheme, the XRP6141 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.| Part No. | XRP6141 |

GENERAL DESCRIPTION
A wide 4.5V to 22V input voltage range allows for single supply operation from industry standard 5V, 12V and 19.6V rails. The control loop also provides exceptional 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 overcurrent, over-temperature, short-circuit and UVLO, help achieve safe operation under abnormal operating conditions. The XRP6141 is available in RoHS compliant, green/halogen free space-saving 16-pin 3x3 QFN package. Rev. 2.0.0APPLICATIONS
