TPS5140 Datasheet - Texas Instruments

TPS5140 4-CHANNEL DC/DC CONTROLLER

The TPS5140 is a dc/dc controller that incorporates three synchronous-buck controllers and one nonsynchronous 12-V boost converter on one chip to power the voltage rails needed by notebook peripheral components. On-chip high-side and low-side synchronous rectifier drivers are integrated to drive les.
