Description
The SC1211VX is a high speed, Combi-Sense®, dual output driver designed to drive high-side and low-side MOSFETs in a synchronous Buck converter. These drivers combined with Combi-Sense® PWM controllers, such as Semtech SC2643VX or SC2643, provide a cost effective multi-phase voltage regulator for advanced microprocessors.


FEATUREs
♦ High efficiency
♦ High peak drive current
♦ Adaptive non-overlapping gate drives provide shoot-through protection
♦ Support Combi-Sense® and VID-on-fly operations
♦ Fast rise and fall times (15ns typical with 3000pf load)
♦ Ultra-low (<30ns) propagation delay (BG going low)
♦ Floating top gate drive
♦ Crowbar function for over voltage protection
♦ High frequency (to 1.5 MHz) operation allows use of small inductors and low cost ceramic capacitors
♦ Under-voltage-lockout
♦ Low quiescent current
♦ Power SOIC-8L package, fully RoHS and WEEE compliant


APPLICATIONs
♦ Intel Pentium® processor power supplies
♦ AMD Athlon™ and AMD-K8™ processor power supplies
♦ High efficiency portable and notebook computers
♦ Battery powered applications
♦ High current low voltage DC-DC converters
