ADP3120A中文资料Dual 12 V MOSFET Driver with Output Disable数据手册ONSEMI规格书

描述 Description

The ADP3120A is a dual, high voltage MOSFET driver optimized for driving two N-channel MOSFETs, the two switches in a nonisolated synchronous buck power converter.Each driver is capable of driving a 3000 pF load with a 45 ns propagation delay and a 25 ns transition time.One of the drivers can be bootstrapped and is designed to handle the high voltage slew rate associated with floating high-side gate drivers.The ADP3120A includes overlapping drive protection to prevent shoot-through current in the external MOSFETs.

特性 Features

• All in one synchronous buck converter
• One PWM generates both drives
• Anti cross-conduction protection circuitry
• Bootstrapped high side driver
• OD for disabling the driver outputs
• Meets CPU VR requirement when used with Flex-Mode controller

应用 Application

• Multiphase CPU supplies
• Single-supply synchonous buck converters
• Desktop computers

简介

ADP3120A属于集成电路（IC）的栅极驱动器。由制造生产的ADP3120A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。
