CL7

100 mA Constant-Current Linear LED Driver with Enable Input

Features

General Description

• 100 mA ±5% Constant-current Driver

• Built-in Reverse Polarity Protection

• Logic-level Enable

The CL7 is a fixed-current linear regulator designed for

driving high-brightness LEDs at 100 mA 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 (with heat slug)

package.

• Dimmable via EN Pin

• Overtemperature Protection

• 90V Maximum Rating for Transient Immunity

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

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

The enable input has 100 kΩ pull-down resistance. For

applications not needing an enable input, refer to the

CL6 data sheet.

Applications

• Flashlights

• Specialty Lighting

• Low-voltage Signage

• Low-voltage Lighting

Overtemperature protection circuitry shuts down all

three channels when the nominal die temperature

reaches 135°C. Normal operation resumes when the

die temperature falls below 105 °C.
