CL6 Linear, Fixed, 100mA Constant Current LED Driver Features ► ► ► ► ► ► General Description The CL6 is a fixed, linear current regulator designed for driving high brightness LEDs at 100mA from nominal 12V, 24V, or 48V supplies. With a maximum rating of 90V, it is able to withstand transients without the need for additional transient protection circuitry. 100mA ±5% constant current drive Built-in reverse polarity protection Dimmable via PWM supply Overtemperature protection Tab ground allows direct heatsinking to chassis 90V max rating for transient immunity The CL6 is offered in both D-PAK and TO-220 packages. The tab on the TO-220 is ground, allowing heatsinking directly to a chassis without the need for electrically insulating spacers. Applications ► ► ► ► ► Flashlights Specialty lighting Low voltage signage Low voltage lighting This device is not rated for automotive applications Overtemperature 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).
