TPS40190 Overview
The TPS40190 is a cost-optimized synchronous buck controller that operates from 4.5 V to 15 V nominally, and implements a fixed frequency voltage mode power supply. The controller uses an adaptive anticross conduction scheme to prevent both the highside and the rectifier MOSFET to be turned on at the same time, preventing shoot through current in the two MOSFETs. The controller also provides a short circuit...
