Supertex CL7 Linear Constant Current
LED Driver with Enable
Supertex CL7 Linear Constant Current LED Driver with Enable 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, Supertex CL7 Linear Constant Current LED Driver is able to withstand transients without the need for additional transient protection circuitry. An active low enable input allows logic level control of the LED for on/off control or PWM dimming. The enable input has 100kΩ pull-down resistance. 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).
