NCV4390_V01規(guī)格書詳情
The NCV4390 is an advanced Pulse Frequency Modulated (PFM)
controller for LLC resonant converters with Synchronous
Rectification (SR) that offers best in class efficiency for isolated
DC/DC converters. It employs a current mode control technique based
on a charge control, where the triangular waveform from the oscillator
is combined with the integrated switch current information to
determine the switching frequency. This provides a better
control?to?output transfer function of the power stage simplifying the
feedback loop design while allowing true input power limit capability.
Closed?loop soft?start prevents saturation of the error amplifier and
allows monotonic rising of the output voltage regardless of load
condition. A dual edge tracking adaptive dead time control minimizes
the body diode conduction time thus maximizing efficiency.
