UL23EB中文资料HIGH ACCURACY LINEAR CONSTANT CURRENT LED DRIVER数据手册UTC规格书

描述 Description

The UL23EB is a linear constant current IC that supports theadjust brightness or color temperature in 3 grades. The applicationscheme is simple and the cost is low.In the dimming application of UL23EB, User can change the sizeof the output current by turn on/off the power switch, that adjustbrightness of LED lights. Changing the REXT external resistanceAdjustment of brightness ratio.In the adjust color temperature application of UL23EB, User canchange the state of the two output ports by turn on/off the powerswitch, that adjust the color temperature through the light of twodifferent colored LED lights. Changing the REXT external resistancecan adjustment the output power.
