XR79115

XR79115 22V, 15A Synchronous Step Down COT Power Module General Description The XR79115 is a 15A synchronous step-down Power Module for point-of load supplies. A wide 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 XR79115 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 0.35% load and 0.1% 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. With a 96% peak efficiency and 90% for loads as low as 100mA, the XR79115 is suitable for applications where low power losses are important. A host of protection features, including over-current, over-temperature, short-circuit and UVLO, help achieve safe operation under abnormal operating conditions. The XR79115 is available in a RoHS compliant, green/halogen free space-saving 68-pin 12x12x4mm QFN package. With integrated controller, drivers, bootstrap diode and capacitor, MOSFETs, inductor, CIN and COUT, this solution allows the smallest possible 15A POL design.
