SC1211VX: High-Speed Combi-Sense® Synchronous MOSFET Driver for Mobile Applications

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.
