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. Atypical 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. Typical Application Circuit Simple 90V, 20mA, Temperature Compensated Constant Current LED Driver IC VA VB Up to 90V + V LED(total) + V LED(total) - VA VB Functional Circuit Diagram CL2 I LED <20mA Control Circuit and Temperature Compensation 100nF |
