Description

CL220 is a high voltage, temperature-compensated, 20mA constant current regulator. The device operates at up to 220V, and is accurate to ±10% over a 5 - 160V range. The device can be used as a two-terminal, con- stant-current source or a constant-current sink. 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. Simple, 220V , 20mA, Temperature-Compensated, Constant-Current, LED Driver IC
