Semtech SC1214
High Speed Combi-Sense® 2-Phase Synchronous MOSFET Driver
The SC1214 is a high speed, Combi-Sense, two-phase driver designed to drive high-side and low-side MOSFETs in two synchronous Buck converters. The driver combined with Combi-Sense PWM controllers, such as Semtech SC2643VX or SC2643, provides a cost effective two-phase voltage regulator for advanced microprocessors.
Overview
Features
- High efficiency
- +12 V gate drive voltage
