Overview

UNISONIC TECHNOLOGIES CO.
, LTD UL23EA Preliminary HIGH ACCURACY LINEAR CONSTANT CURRENT LED DRIVER  DESCRIPTION The UL23EA is a linear constant current IC that supports the adjust brightness or color temperature in 3 grades.
The application scheme is simple and the cost is low.
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.
 FEATURES * Input voltage 220VAC, 110VAC * Adjustable output current, max 60mA * Inter-chip current deviation < ±4% * Application system no EMI problems * Over temperature Reduced Current * Supports the adjust brightness in 3 grades * Supports the adjust color temperature in 3 grades * In no stroboscopic apply: Power factor > 0.
5 * No transformer and high voltage electrolysis capacitor: Power factor > 0.
9 * Effectively switching time from 0.
