1 pcs : NCV4390DR2G - Switching Controllers Automotive Advanced Secondary Side LLC Resonant Converter Controller with Synchronou

NCV4390 Automotive Resonant Converter Controllers onsemi NCV4390 Automotive Resonant Converter Controllers are designed for LLC resonant converters with Synchronous Rectification (SR). The controller offers best-in-class efficiency for isolated DC/DC converters. The NCV4390 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.
