NCP81151B中文资料VR12.5 MOSFET 驱动器数据手册ONSEMI规格书

描述 Description

The NCP81151B is a high performance dual MOSFET gate driver optimized to drive the gates of both high−side and low−side power MOSFETs in a synchronous buck converter. It can drive up to 3 nF load with a 25 ns propagation delay and 20 ns transition time. Adaptive anti−cross−conduction and power saving operation circuit
can provide a low switching loss and high efficiency solution for notebook systems.
The UVLO function guarantees the outputs are low when the supply voltage is low.

特性 Features

• Output disable Control Turns off both MOSFETs
• Prevents Short Circuit
• Faster Rise and Fall Times

应用 Application

• Vcore Power
• Notebooks

简介

NCP81151B属于集成电路（IC）的栅极驱动器。由制造生产的NCP81151B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。
