SC1218: High-Speed 12 V Synchronous Power MOSFET Driver

The SC1218 is a high speed, robust, dual output driver to drive high-side and low-side N-MOSFETs in synchronous buck converters. Combined with Semtech’s multi-phase PWM controller SC2649, one can build high performance, versatile voltage regulators for next generation microprocessors.
