Overview
NCP5901B VR12 Compatible Synchronous Buck MOSFET Drivers The NCP5901B 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 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 under−voltage lockout function guarantees the outputs are low when supply voltage is low.
Features • Faster Rise and Fall Times • Adaptive Anti−Cross−Conduction Circuit • Integrated Bootstrap Diode • Pre OV function • ZCD Detect • Floating Top Driver Accommodates Boost Voltages of up to 35 V • Output Disable Control Turns Off Both MOSFETs • Under−voltage Lockout • Power Saving Operation Under Light Load Conditions • Direct Interface to NCP6151 and Other Compatible PWM Controllers • Thermally Enhanced Package • These are Pb−Free Devices Typical Applications • Power Solutions for Desktop Systems http://onsemi.
