NCP5339数据手册集成电路（IC）的全半桥驱动器规格书PDF

描述 Description

The NCP5339 integrates a MOSFET driver, high side MOSFET and low side MOSFET into a 6 mm x 6 mm QFN-40 package. The driver and MOSFETs have been optimized for high current, multi-phaseDC to DC buck power conversion applications. The NCP5339 integrated solution greatly reduces package parasitics and board space compared to a discrete component solution.

特性 Features

• Switching frequency up to 1MHz
• Optimize trade-off between efficiency versus board space and passive count
• Capable of output currents up to 50A
• High power capability reduces number of phases
• Internal bootstrap diode
• Reduce board space
• Zero current detection
• Better light load efficiency
• Undervoltage lockout
• Ensure proper operation during power up/power down
• Internal thermal warning / thermal shutdown
• Thermal protection
• Thermally enhanced package
• Power better power dissipation

应用 Application

• FPGA power
• Network processors
• Base stations
• storage
• servers
• Servers
• Video cards
• base stations
• network switch
• server/storage

简介

NCP5339属于集成电路（IC）的全半桥驱动器。由制造生产的NCP5339全半桥驱动器器件属于电桥驱动器电源管理集成电路 (PMIC) 系列，包含两个或多个功率晶体管，以及在外部器件控制下将其用作开关所需的电路。这些晶体管通常在内部配置为成对串联连接（称为半桥），因而任意指定晶体管对之间的结点都可以连接至两个电源轨中的任一个。这类器件常用于将控制器件（如微控制器）提供的低电平信号转换为操作执行器（如步进电机或无刷电机）所需的较大功率信号。
