CL2K4

CL2 Initial Release Simple 90V 20mA Temperature Compensated Constant Current LED Driver IC Features 5.0V to 90V operating range (VA-B) 20mA ±10% at 5-90V 0.01% / °C Typical Temperature Coefficient TO-243AA (SOT-89), TO-252 (D-PAK), & TO-92 packages No external components (two terminal device) Can be paralleled for higher current General Description The Supertex CL2 is a high voltage, temperature compensated, constant current source. The device is trimmed to provide a constant current of 20mA±10% at an input voltage of 5-90V. No external components are required. The device can be used as a two terminal constant current source or constant current sink. A typical application for the CL2 is to drive LEDs with a constant current of 20mA. They can also be used in parallel to provide higher currents such as 40mA, 60mA or 80mA. The device is available in SOT-89, TO-252 (D-PAK), and TO-92 packages.
