NCL30159AADR2G

NCL30159AADR2G is an LLC converter controller with an HB driver. It is a primary side current mode LLC controller. The controller is eligible for lighting application with minimum external components. The control technique optimizes switching frequency depending on the energy of the resonant tank. This controller allows to implementation of many features (high efficiency in standby, open string protection, dedicated startup. Also can provide wide dimming range operation in wide output conditions. The high-voltage section featuring the high-voltage startup and brown-out detection greatly simplifies the design of the power supply or LED string driver. The Analog dimming feature together with the PWM dimming allows to control of the total light flux from the LED string this feature allows to design of the window LED driver as well. It is used in applications such as low-cost high-efficiency LED lighting 50 to 300W, EV battery chargers, and TV set power supply.
