NCP4303規(guī)格書詳情
The NCP4303A/B is a full featured controller and driver tailored to
control synchronous rectification circuitry in switch mode power
supplies. Thanks to its versatility, it can be used in various topologies
such as flyback, forward and Half Bridge Resonant LLC.
The combination of externally adjustable minimum on and off times
helps to fight the ringing induced by the PCB layout and other
parasitic elements. Therefore, a reliable and noise less operation of the
SR system is insured.
The extremely low turn off delay time, high sink current capability
of the driver and automatic package parasitic inductance
compensation system allow to maximize synchronous rectification
MOSFET conduction time that enables further increase of SMPS
efficiency.
Finally, a wide operating VCC range combined with two versions of
driver voltage clamp eases implementation of the SR system in 24 V
output applications.
