High-Voltage Half-Bridge

Driver with Inbuilt

Oscillator

The NCP1393B 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 guarantees 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 to lower

the shoot−through current.
