XR76120 Description
The XR76116 and XR76120 are synchronous step-down regulators bining 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.
