SC1218
High Speed
Synchronous MOSFET Driver
Revision: October 14, 2005
Features
Applications
Typical Application Circuit
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 micropro-
cessors.
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.
