Description

The SC1214 is a high speed, Combi-SenseTM, 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

♦ +12V gate drive voltage

♦ 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
