Complete PoE Connected LED Driver Power Solution, IEEE 802.3bt NCL31010 Description The NCL31010 is a member of the onsemi Power over Ethernet Powered Device (PoE−PD) product family and integrates an IEEE 802.3bt PoE−PD interface controller, a dual step−down converter and a buck convertor LED driver. The NCL31010 incorporates all the required functions for operation within a PoE system such as detection, classification and current limiting during the inrush phase. The NCL31010 contains synchronous step−down DC/DC converters for the main 3.3 V system supply as well as an auxiliary supply. In addition, the NCL31010 also integrates a current mode buck DC/DC controller designed to operate as a LED driver. The LED driver supports both PWM dimming and high−bandwidth analog dimming.
