Description

General part information

NCP4318 Series

NCP4318 is a mixed mode, which uses instantaneous drain voltage and previous dead time information, Synchronous Rectification (SR) controller for LLC resonant converter with minimum external components. The adaptive dead time control compensates induced parasitic inductance voltage to maximize SR MOSFET conduction and the efficiency. Multi-step turn-off threshold control and SR current inversion detection function prevent inversion current during fast load transient and allows stable SR operation over entire load range. In addition, to improve light load efficiency, VGATE is adaptively reduced from 10V to 6V/5V.
