Datasheet - NCP4390DR2G

The ON Semiconductor 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.

Excellent transient response and easy feedback loop design
Adaptive SR withdDual edge tracking
Best In class efficiency
