NCP4390DR2G規(guī)格書詳情
The NCP4390 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.
Features

? Wide Operating Frequency (39 kHz ~ 690 kHz)
? Green Functions to Improve Light?Load Efficiency
? Symmetric PWM Control at Light?Load to Limit the Switching
Frequency while Reducing Switching Losses
? Disabling SR at Light?Load Condition
? Protection Functions with Auto?Restart
? Over?Current Protection (OCP)
? Output Short Protection (OSP)
? NON Zero?Voltage Switching Prevention (NZS) by
Compensation Cutback (Frequency Shift)
? Power Limit by Compensation Cutback (Frequency Shift)
? Overload Protection (OLP) with Programmable Shutdown Delay Time
? Programmable Dead Times for Primary Side Switches and Secondary
Side Synchronous Rectifiers
? VDD Under?Voltage Lockout (UVLO)
? Wide Operating Temperature Range ?40°C to +125°C
? This Device is Pb?Free, Halogen Free/BFR Free and is RoHS Compliant
Applications
? Automotive On Board Charger
? Intelligent 100 W?2 kW+ Off?Line & Industrial Power Supplies
