Low voltage differential constant current IC scheme -


Ultra low voltage differential starting universal linear constant current IC, independent VDD can be easily applied to various input voltage situations, directly connected in series to the LED string circuit, with only one peripheral resistor required. The current of the LED string circuit can be changed by adjusting the resistor, without any magnetic devices, and has good EMC characteristics. Simultaneously compatible with PWM dimming, second line dimming, and analog dimming.



Features:


The output current is adjustable, and the required current can be adjusted arbitrarily;


Start at ultra-low voltage of 0.15V;


Parallel connection can increase the current;


◆ Only one resistor is needed on the periphery, without the need for inductance, capacitance, or magnetic devices


◆ High constant current accuracy, within+/-3%;


◆ Compatible with PWM dimming, two line dimming, and analog dimming


◆ Suitable for occasions with 12V, 24V, 36V, 48V, 64V voltage inputs, etc
