Semtech SC1211VX

High-Speed Combi-Sense® Synchronous MOSFET Driver for Mobile Applications

Add to Watch List

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
