NIS3001
Integrated Driver and
MOSFET Power Chip for
Synchronous Buck
Controllers
The NIS3001 is an integrated multi−chip solution for high power
DC to DC synchronous buck converters. It contains two power
MOSFETs that are controlled by an internal Driver. All three die are
packaged in a power QFN package called PInPAK™. The 10.5 by
10.5 mm PInPAK™ package increases power density and simplifies
PCB layout. The device can be used in single or multi−phase
applications.
The NIS3001 implements the newest MOSFET technology. The
control MOSFET is designed to provide improved switching
performance and operates at a much lower temperature compared to
discrete solutions. The synchronous MOSFET is designed to reduce
conduction and switching losses at high frequencies. The integrated
solution greatly reduces the parasitic inductance associated with
conventional discrete buck converters and results in the highest
power conversion efficiency.
The power density of the NIS3001 is optimized based on MOSFET
die size and PInPAK design. The PInPAK layout allows for direct
routing into each power terminal. This results in a better thermal
solution for the system. In addition its thermal rDesaistataSnhceeeits4U50.c%om
lower than BGAs. In summary, the NIS3001 has an improved
efficiency, reliability and scalability for multi−phase synchronous
buck converters.
