Semtech SC1214

High Speed Combi-Sense® 2-Phase Synchronous MOSFET Driver

Add to Watch List

The SC1214 is a high speed, Combi-Sense, two-phase driver designed to drive high-side and low-side MOSFETs  in two synchronous  Buck  converters. The driver combined with Combi-Sense PWM controllers, such as  Semtech  SC2643VX or SC2643, provides a cost effective two-phase  voltage regulator for advanced microprocessors.


  • High efficiency
  • +12 V gate drive voltage
  • 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 (15 ns typical with 3000 pf load)
  • Ultra-low (<30 ns) 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
  • TSSOP-20 package


  • Intel Pentium® processor power supplies
  • AMD Athlon™ and K8™ processor power supplies
  • High-current low-voltage DC-DC converters
