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 Power SO-8 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.
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).
