Overview

The SC1211VX is a high speed, Combi-Sense, dual output driver designed to drive high-side and low-side MOSFETs‚  in‚  a synchronous‚  Buck‚  converter. These drivers combined with Combi-Sense PWM controllers, such as Semtech SC2643VX or SC2643, provide a cost effective multi-phase voltage regulator for advanced microprocessors.
