CL220N5-G Microchip

CL220 Simple, 220V, 20mA, Temperature-Compensated, Constant-Current, LED Driver IC Features Description 5.0 to 220V operating range (V ) A-B CL220 is a high voltage, temperature-compensated, 20mA 10% at 5.0 - 160V 20mA constant current regulator. The device operates 0.01% / C typical temperature coefficient at up to 220V, and is accurate to 10% over a 5 - 160V range. The device can be used as a two-terminal, con- Packages Types: stant-current source or a constant-current sink. - TO-252 (D-PAK) -TO-220 A typical application for CL220 is to drive LEDs with a Can be paralleled for higher current constant current of 20mA. Multiple CL220s can also be used in parallel to provide higher currents such as Applications 40mA, 60mA, 80mA, and so on. The device is available in the TO-252 (D-PAK) and TO-220 packages.
