NCP5359 Gate Driver for Notebook Power Systems
The NCP5359 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. Each of the drivers can drive up to 3 nF load with a 25 ns propagation delay and 20 ns transition time. Adaptive nonoverlap and power saving operation circuit can provide a low switching loss and high efficiency solution for notebook and desktop systems. A high floating top driver design can accommodate VBST voltage as high as 35 V, with transient voltages as high as 35 V. Bidirectional EN pin can provide a fault signal to controller when the gate driver fault detect under OVP, UVLO occur.
