CL330
General Description
The CL330 is designed to drive 3 strings of LEDs at a
constant current of 30mA.
Other drivers with currents in the range of 20 - 30mA are
available. The drive current is fixed, with a ±6% tolerance
over a V
OUT
range of 4 - 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.
