ULD5121规格书详情
描述 Description
UTC ULD5121 is a controller, which drives external NMOSFETto remove the 100/120Hz LED current ripple on AC/DC power by acapacitor between VC and GND. The chip ensures minimum powerdissipation on NMOSFET while removing LED current ripple relyingon the adaptive technology.UTC ULD5121 allows user to setup the maximum cathodevoltage of LED string by sensing the drain voltage of NMOSFETwhich could help limit the power dissipation on chip.
