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.
