SC1211数据手册集成电路（IC）的PMIC-稳压器-DCDC开关式控制器规格书PDF

描述 Description

The SC1211 is a high speed, Combi-Sense, dual output driver designed to drive high-side and low-side MOSFETs in a synchronous Buck converter. These drivers combined with Combi-Sense PWM controllers, such as Semtech SC2643VX or SC2643, provide a cost effective multi-phase voltage regulator for advanced microprocessors.

特性 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
·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

应用 Application

·Intel Pentium® processor power supplies
·AMD Athlon™ and AMD-K8™ processor power supplies
·High-current low-voltage DC-DC converters

简介

SC1211属于集成电路（IC）的PMIC-稳压器-DCDC开关式控制器。由制造生产的SC1211DC-DC 开关控制器PMIC（电源管理集成电路）DC 到 DC 开关式控制器是用于高效率电路的稳压 IC，其配置为生成高于（突升或步升）或低于（突降或步降）输入电源的输出电源电压。其他拓扑结构可能包括：降压-升压、反激、正激、Cuk、SEPIC、全桥、半桥和推挽式。这些器件不同于需要最小电压并“烧尽”多余电压的线性稳压器。
