CL330 Datasheet | Supertex

Features - ±6.0% current accuracy @ 4.0 -15V - 90V standoff voltage - Separate enable pins for each channel allow for PWM dimming - Over-temperature protection - 8-Lead SOIC (w/Heat Slug) package Applications - LCD backlighting - Indicator lamps General Description The CL330 is designed to drive 3 strings of LEDs at a constant current of 30m A. Other drivers with currents in the range of 20 - 30m A are available. The drive current is fixed, with a ±6% tolerance over a VOUT range of 4.0 - 15V. Separate enable pins for each channel allow for PWM dimming, 3-step linear dimming, or individual disconnection of faulty LED strings. Over-temperature protection circuitry shuts down all 3 channels when the nominal die temperature reaches 135°C. Normal operation resumes when the die temperature drops by 30°C. The CL330 is available in the 8-Lead SOIC (w/Heat Slug) package and requires a single ceramic bypass capacitor which may be shared among several drivers.
