DESCRIPTION
The XR76116 and XR76120 are synchronous step-down regulators combining the controller, drivers, bootstrap diode and MOSFETs in a single package for point-of-load supplies. The XR76116 has a load current rating of 15A and the XR76120 has a load current rating of 20A. 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 0.1% 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. A host of protection features, including overcurrent, over temperature, overvoltage, short-circuit, open feedback detect and UVLO, helps achieve safe operation under abnormal operating conditions. The XR76116/20 are available in a RoHS-compliant, green/halogenfree space-saving 5mm x 6mm QFN package. FEATURES
