onsemi NCL30059BDR2G

The NCL30059 is a self−oscillating high voltage MOSFET driver primarily tailored for LED driver applications using half−bridge topology. LLC and LCC configurations are supported with optimized wide range control offered by the latter for Constant Current (CC) applications. Due to its proprietary 600 V technology, the driver is useful for bulk voltages utilized in 277 VAC lighting applications. 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 ensures the converter is enabled after the bulk voltage is fully stabilized. The device provides fixed dead−time which helps to lower the shoot−through current.
