TPS40190 Datasheet (Texas Instruments) - Synchronous Buck Controller

TPS40190, Synchronous Buck Controller

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 th
