NCL31010
Description
The NCL31010 is a member of the onsemi Power over Ethernet
Powered Device (Po E- PD) product family and integrates an IEEE 802.3bt Po E- 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 Po E 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.
The NCL31010 supports high- power applications (up to 90 W Po E).
