NCP1392B_09 Datasheet, PDF (1/21 Pages) ON Semiconductor – High-Voltage Half-Bridge Driver with Inbuiltc Oscillator

NCP1392B, NCP1392D
High-Voltage Half-Bridge
Driver with Inbuilt
Oscillator
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.
