NCL 30159 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 energy of resonant tank. This controller allows to

implement many features (high efficiency in standby, open string

protection, dedicated startup…). Also can provide wide dimming

range operation in wide output condition. Housed in a SOIC?16

package it integrates half?bridge output drivers together with the

primary current sensing.

High?Voltage section featuring the High?Voltage startup and

Brown?out detection greatly simplifies the design of the power supply

or LED string driver. Analog Dimming feature together with the PWM

dimming allows to control the total light flux from the LED string this

feature allows to design the window LED driver as well.

This controller allows to ensure the maximum power limit feature.

This advantage is useful for designing the wide input voltage range

converters or the LED drivers with their output matched to different

LED strings.
