NCP5901B中文资料MOSFET Driver, VR12 Compatible, Synchronous Buck数据手册ONSEMI规格书

描述 Description

NCP5901 is a high performance dual MOSFET driver optimized to drive the gates of both high- and low-side power MOSFETs in a synchronous buck converter. It can drive up to a 3.0 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 and desktop systems. Bidirectional EN pin can provide a fault signal to controller when the gate driver fault detect under OVP, UVLO occur. Also, an undervoltage lockout function guarantees the outputs are low when supply voltage is low.

特性 Features

• Fast rise and fall times
• Adaptive anti-cross-conduction circuit
• Pre-overvoltage function

应用 Application

• Vcore Power Subsystems
• Desktop Computers
