NCP5358
Gate Driver for Desktop
Power Systems
The NCP5358 is a high performance two channel gate driver. It
combines two single NCP5359 gate drivers together and provides an
optimized solution for multi−phase application. Each channel gate
driver has both high−side and low side power MOSFETs in a
synchronous buck converter. Also, it can drive up to 3 nF load with a
25 ns propagation delay and 20 ns transition time.
An adaptive non−overlap and power saving operation circuit has
built in. It can provide a low switching loss and high efficiency
solution in notebook and desktop systems. Thus, this controller has
three protection functions, under voltage lockout (UVLO), over
voltage protection (OVP) and thermal shutdown.
The NCP5358 is available in 4x4 mm QFN16 package.
