Overview
The SC1210 is a high speed, dual output driver designed to drive high-side and low-side MOSFETs in a synchronous Buck converter. These drivers can work with many Semtech PWM controllers to provide a cost effective multi-phase voltage regulator for advanced microprocessors.
Features
- High-efficiency dual MOSFET driver
- +12 V supply voltage with internal LDO for optimum gate drive
- High peak drive current
- Adaptive non-overlapping gate drives provide shoot-through protection
- 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
- Standard SO-8 package
Applications
- Intel Pentium® processor power supplies
- AMD Athlon™ and AMD-K8™ processor power supplies
- High-current low-voltage DC-DC converters
