NCP4307AASNT1G規(guī)格書詳情
The NCP4307 is high performance driver tailored to control a
synchronous rectification MOSFET in switch mode power supplies.
Thanks to its high performance drivers and versatility, it can be used in
various topologies such as DCM or CCM flyback, quasi resonant
flyback and forward.
Internal minimum off?time and on?time blanking periods help to
fight the ringing induced by the PCB layout and other parasitic
elements. A reliable and noise less operation of the SR system is
ensured due to the Self Synchronization feature. The NCP4307 also
utilizes Kelvin connection of the driver to the MOSFET to achieve
high efficiency operation at full load and utilizes a light load detection
architecture to achieve high efficiency at light load.
The precise turn?off threshold, extremely low turn?off delay time
and high sink current capability of the driver allow the maximum
synchronous rectification MOSFET conduction time and enables
maximum SMPS efficiency.
Self?supply capability allows to use NCP4307 in high side
configuration and/or in low output voltage SMPS without auxiliary
winding or other power source.
