NCL30059BDR2G

NCL30059BDR2G is a high-voltage half-bridge controller for LED lighting applications. It 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 600V technology, the driver is useful for bulk voltages utilized in 277VAC lighting applications. Operating frequency of the driver can be adjusted from 25KHz to 250KHz using a single resistor. Adjustable brown-out protection assures correct bulk voltage operating range. An internal 100ms 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. Applications includes LED electronic control gear, LED driver power supplies, power supplies for LED signage, AC-DC low ripple LED drivers.
