DESCRIPTION
The LM5115 is a versatile switching regulator controller. It has two main application configurations. The first is utilizing the Secondary Side Post Regulation (SSPR) technique to implement multiple output power converters. In the second configuration, it can be used as a standalone synchronous buck controller (Please see Standalone DC/DC Synchronous Buck Mode for more details). The SSPR technique develops a highly efficient...
