CL2K4-G LED Driver ICs by Microchip Technology

Simple 90V, 20mA, Temperature Compensated, Constant-Current LED Driver IC


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 5.0 - 90V. 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. Multiple CL2s can also be used in parallel to provide higher currents such as 40mA, 60mA or 80mA. The device is available in TO-243AA (SOT-89), TO-252 (D-PAK), and TO-92 packages.
