NCP5901B: MOSFET Driver, VR12 Compatible, Synchronous Buck

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.

Features
  • Fast rise and fall times
  • Adaptive anti-cross-conduction circuit
  • Pre-overvoltage function
Applications
  • Vcore Power Subsystems
End Products
  • Desktop Computers
