SC1214
Product is not recommended for new design.
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.
Features
- 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
