UNISONIC TECHNOLOGIES CO., LTD UPSLD01 Preliminary CMOS IC HIGH POWER FACTOR LINEAR CONSTANT CURRENT LED DRIVER DESCRIPTION UTC UPSLD01 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.

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=0.55V/R IOUT2=0.70V/R IOUT3=0.85V/R IOUT4=0.90V/R UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 4 of 5 QW-R125-036.b UPSLD01 CMOS IC TYPICAL APPLICATION CIRCUIT 38×2 24×2 11×2 10×2 VIN Vac UTC UPSLD01 5 REXT OUT1 4 6 NC OUT2 3 7 NC OUT3 2 30R 8 GND OUT4 1 Figure 1.
