DESCRIPTION
In the dimming application of UL23EA, user can change the size of the output current by turn on/off the power switch, that adjust brightness of LED lights. Changing the REXT external resistance adjustment of brightness ratio. In the adjust color temperature application of UL23EA, user can change the state of the two output ports by turn on/off the power switch, that adjust the color temperature through the light of two different colored LED lights. Changing the REXT external resistance can adjustment the output power.●
