SC1210 Datasheet - Semtech Corporation

Description
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
♦ +12V 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 (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 K8™ processor power supplies
♦ High current low voltage DC-DC converters
