SC1218  
High Speed  
Synchronous MOSFET Driver  
POWER MANAGEMENT  
Features  
Description  
The SC1218 is a high speed, robust, dual output driver to ‹ Advanced Digital Timing to Filter Out Very Narrow PWM  
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.  
Pulses  
‹ +12V Gate Drive Voltage  
‹ Integrated Bootstrap Diode  
‹ High Peak Drive Current  
‹ Adaptive Non-overlapping Gate Drives Provide Shoot-  
through Protection  
‹ Support Dynamic VID operation  
‹ Ultra-low Propagation Delay  
‹ Floating Top Gate Drive  
‹ Crowbar Function for Over Voltage Protection  
‹ High Frequency (up to 2 MHz) Operation Allows Use of  
Small Inductors and Low Cost Ceramic Capacitors  
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 ‹ Under Voltage Lockout  
both SOIC-8 package and MLPQ-8 3x3mm package. These  
features further reduce the thermal stress and BOM cost.  
‹ Low Quiescent Current  
‹ Enable Function for Both Gate OFF Shut Down  
‹ Lead-free Part and Fully WEEE and RoHS Compliant  
Applications  
‹ Intel Next Generation Processor Power Supplies  
‹ AMD AthlonTM and AMD-K8TM Processor Power  
Supplies  
‹ High Current Low Voltage DC-DC Converters
