General Description

The CL7 is a linear fixed current regulator designed for

driving high brightness LEDs at 100mA from nominal 12V,

24V, and 48V power supplies. With a maximum rating of

90V, it is able to withstand transients without the need for

additional transient protection circuitry. The CL7 is offered

in the 8-Lead SOIC package.

An active low enable input (EN) allows logic level control

of the LED for on/off control or PWM dimming. The enable

input has 100kΩ pull-down resistance. For applications not

needing an enable input, refer to the CL6 data sheet.

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).
