Supertex inc. CL6 Linear, Fixed, 100mA, Constant Current LED Driver Features General Description 100mA 5% constant current drive The CL6 is a fixed, linear current regulator designed for driving high brightness LEDs at 100mA from nominal 12V, Built-in reverse polarity protection 24V, or 48V supplies. With a maximum rating of 90V, it is Dimmable via PWM supply able to withstand transients without the need for additional Overtemperature protection transient protection circuitry. Tab ground allows direct heatsinking to chassis 90V max rating for transient immunity 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 Applications electrically insulating spacers. Flashlights Specialty lighting Overtemperature protection shuts off the LED current when Low voltage signage the die temperature rises above 135C (nominal). Full LED Low voltage lighting current resumes when the die temperature falls below 105C (nominal). Typical Application Circuit V IN 100mA VDD OUT Control GND CL6 Doc. DSFP-CL6 Supertex inc.
