Description

The NCL 30159 is a primary side current mode LLC controller. The controller can provide wide dimming range operation in wide output condition. This controller allows to implement many features (high efficiency in standby, open string protection, dedicated startup). And allows to ensure the maximum power limit feature. It enable to design the wide input voltage range converters or the LED drivers with their output matched to different LED strings.
