Microchip Technology CL220 LED Drivers

Microchip's CL220 LED Drivers are designed to drive a string of LEDs with a constant current of 20mA, and multiple ICs can be used in parallel to provide higher output currents in increments of 20mA. The CL220 LED Drivers can be used in a variety of solid-state lighting applications, such as signage, automotive, industrial indicators, and accent lighting. Microchip's CL220 LED Drivers operates from 5 to 220V and is trimmed to provide a constant output current of 20mA (+/-10%) at an input voltage of 5 to 160V.
