Semtech SC1211
High-Speed Combi-Sense™ Synchronous MOSFET Driver
The SC1211 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
- +12V supply voltage with internal LDO for optimum gate drive
- High peak drive current
- Adaptive non-overlapping gate drives provide shoot-through protection
- Support Combi-SenseTM 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
Applications
- Intel Pentium® processor power supplies
- AMD Athlon™ and AMD-K8™ processor power supplies
- High-current low-voltage DC-DC converters
