NCP1392B SOP8

High-Voltage Half-Bridge Driver with Inbuilt Oscillator NCP1392B, NCP1392D The NCP1392B/D is a self−oscillating high voltage MOSFET driver primarily tailored for the applications using half bridge topology. Due to its proprietary high−voltage technology, the driver accepts bulk voltages up to 600 V. Operating frequency of the driver can be adjusted from 25 kHz to 480 kHz using a single resistor. Adjustable Brown−out protection assures correct bulk voltage operating range. An internal 100 ms or 12.6 ms PFC delay timer guarantee that the main downstream converter will be turned on in the time the bulk voltage is fully stabilized. The device provides fixed dead time which helps lowering the shoot−through current.
