NCP1392B
High-Voltage Half-Bridge
Driver with Inbuilt
Oscillator
The NCP1392B 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 250 kHz using a single resistor. Adjustable
Brown−out protection assures correct bulk voltage operating range.
An internal 100 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.
