SC1210STR中文资料升特数据手册PDF规格书

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
