CL220  
Simple, 220V, 20mA,  
Temperature-Compensated, Constant Current,  
LED Driver IC  
Features  
General Description  
► 5.0 to 220V operating range (VA-B)  
The Supertex CL220 is a high voltage, temperature-  
compensated, 20mA constant current regulator. The device  
operates at up to 220V, and is accurate to ±10% over a 5.0  
- 160V range. The device can be used as a two terminal  
constant current source or constant current sink.  
► 20mA ±10% at 5.0 - 160V  
► 0.01% / °C typical temperature coefficient  
► Available in TO-252 (D-PAK) and TO-220 packages  
► Can be paralleled for higher current  
A typical application for the CL220 is to drive LEDs with  
a constant current of 20mA. Multiple CL220s can also be  
used in parallel to provide higher currents such as 40mA,  
60mA, 80mA, and so on. The device is available in the TO-  
252 (D-PAK) and TO-220 packages.  
Applications  
► Industrial lamp indicators  
► Signage  
► Accent lighting  
► Constant current source  
► Constant current sink
