Semtech SC1211
High-Speed Combi-Sense™ Synchronous MOSFET Driver

Not recommended for new designs.
Overview
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
Packaging
- SOIC-8 EDP
