Typical Application Circuit
General Description
The CL6 is a xed, 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.
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).

Absolute Maximum Ratings are those values beyond which damage to the device may
occur. Functional operation under these conditions is not implied. Continuous operation
of the device at the absolute rating level may affect device reliability. All voltages are
referenced to device ground.
