Applications

‰ LED driver ‰ Industrial lamp indicators ‰ Signage ‰ Accent lighting ‰ Automotive ‰ Constant current source ‰ Constant current sink Typical Application Circuit 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.

Absolute Maximum Ratings* VA-B, Operating Voltage 100V TJ, Operating Junction Temperature -40°C to +125°C Ts, Storage Temperature -55°C to +150°C *Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is not implied. Continuous operation of the device at the absolute rating level may affect device reliability.
