The CL6K4-G is a linear fixed constant current LED Driver designed for driving high brightness LEDs at 100mA from nominal 12/24/48V supplies. With a maximum rating of 90V, it is able to withstand transients without the need for additional transient protection circuitry. The CL6 regulator with tab on the TO-220 is ground, allowing heat-sinking directly to a chassis without the need for electrically insulating spacers. Over-temperature protection shuts OFF the LED current when the die temperature rises above 135°C nominal. Full LED current resumes when the die temperature falls below 105°C nominal.
