SC1214数据手册集成电路（IC）的栅极驱动器规格书PDF

描述 Description

The SC1214 is a high speed, Combi-Sense, 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.

特性 Features

·High efficiency
·+12 V gate drive voltage
·High peak drive current
·Adaptive non-overlapping gate drives provide shoot-through protection
·Support Combi-Sense™ and VID-on-fly operations
·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
·TSSOP-20 package

应用 Application

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

简介

SC1214属于集成电路（IC）的栅极驱动器。由制造生产的SC1214栅极驱动器栅极驱动器电源管理集成电路 (PMIC) 可用于提供隔离、放大、参考位移、自举或其他必要功能，这些功能可将来自电源转换应用中控制设备的信号连接到电源被控制通过的半导体设备（通常为 FET 或 IGBT）。任何特定设备提供的确切功能各不相同，但与它适合驱动的半导体配置相关。
