DESCRIPTION
UTC UALD11060 is a high power factor linear constant current
LED driver which is applied to LED lighting. Through the distinctive
constant current control technology, it realizes that constant current
accuracy is less than ±5% and output current is adjustable through
external resistor. High power factor and low harmonic distortion are
the particular features.
The system is simple without transformer and electrolysis
capacitor. Therefore, LED lighting batch job can be realized.

FUNCTIONAL DESCRIPTION
UTC UALD11060 is constant current drive which integrates the functional module such as LED constant current
control and OUT port high voltage drive. OUT1 port minimum input voltage is 6V (IOUT=20mA)and it can reach
output current 10mA ~ 60mA by external REXT resistor. Built-in LED constant current drive maintains LED current a
high precision without impact of ambient temperature. The chip can achieve high efficiency and high power factor by
opening four switches one by one.
The chip output current is adjustable by REXT resistor IOUT=VREXT/R. Output current generated by four switches
opening one by one is shown below:
IOUT1=0.57V/R
IOUT2=0.73V/R
IOUT3=0.87V/R
IOUT4=0.95V/R
