CL320/CL325/CL330

3-Channel Linear LED Drivers

Features

General Description

• ±6% Current Accuracy when V_OUTis between 4V

and 15V

The CL320/CL325/CL330 are designed to drive three

strings of LEDs at a constant current of 20 mA, 25 mA

and 30 mA, respectively.

• 90V Standoff Voltage

• Separate Enable Pins for each Channel for PWM

Dimming

The drive current is fixed, with a ±6% tolerance over a

V_OUTrange of 4V to 15V. Separate enable pins for

each channel allow for PWM dimming, three-step linear

dimming or individual disconnection of faulty LED

strings.

• Overtemperature Protection

• 8-Lead SOIC (with Heat Slug) Package

Overtemperature protection circuitry shuts down all

three channels when the nominal die temperature

reaches 135°C. Normal operation resumes when the

die temperature drops by 30°C.

Applications

• LCD Backlighting

• Indicator Lamps

The CL320/CL325/CL330 are available in the 8-lead

SOIC (with heat slug) package and require a single

ceramic bypass capacitor which may be shared among

several drivers.
