SC1218

POWER MANAGEMENT Description 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. SC1218 is built upon a CMOS technology which provides enough voltage capacity to handle computer applications. In addition, the advanced timing circuitry is adopted to filter out very narrow PWM pulses at the input of the driver. The latched UVLO and enhanced adaptive shoot-through protection further enhance the robustness of the SC1218. With integrated bootstrap diode, the SC1218 is offered in both SOIC-8 package and MLPQ-8 3x3mm package. These features further reduce the thermal stress and BOM cost.
