TPS546E25 Overview
The TPS546E25 device is a highly integrated, buck converter with D-CAP4 control topology for fast transient response. All programmable parameters can be configured by the PMBus interface and stored in NVM as the new default values to minimize the external ponent count. Pinstrap options allow for configuration as primary or secondary, stack position and stack number, DCM (single phase only) or FCCM, overcurrent...
