Supertex inc. CL6 Linear, Fixed, 100mA, Constant Current LED Driver Features General Description ►► 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 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. The CL6 is offered in both TO-252 (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 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).
