NCP1393B
High-Voltage Half-Bridge
Driver with Inbuilt
Oscillator
The NCP1393B is a selfâoscillating high voltage MOSFET driver
primarily tailored for the applications using halfâbridge topology. Due
to its proprietary highâvoltage 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
brownâout protection assures correct bulk voltage operating range. An
internal 100 ms PFC delay timer guarantees that the main downstream
converter will be turned on in the time the bulk voltage is fully
stabilized. The device provides fixed deadâtime which helps to lower
the shootâthrough current.
