TPS5140 - 4-CHANNEL DC/DC CONTROLLER

Datasheet Summary

Description

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.

Features

  • dead-time control and very low quiescent current. Resistorless current protection and the fixed high-side driver voltage simplify the system design and reduce the external parts count. Please be aware that an important notice concerning availability, standard warranty, and use in critical.
