DESCRIPTION
A typical application for 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. 2015 Microchip Technology Inc.
