GENERAL DESCRIPTION
A wide 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 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. FEATURES
