The NCL30059B is a self−oscillating high voltage MOSFET driverprimarily tailored for LED driver applications using half−bridgetopology. LLC and LCC configurations are supported with optimizedwide range control offered by the latter for Constant Current (CC)applications. Due to its proprietary 600 V technology, the driver isuseful for bulk voltages utilized in 277 VAC lighting applications.
