产品型号CL320的Datasheet PDF文件预览

CL320  
3-Channel 20mA Linear LED Driver  
Features  
±±6 current accuracy ꢀ 4.0 -15V  
90V standoff voltage  
General Description  
The CL320 is designed to drive 3 strings of LEDs at a  
constant current of 20mA.  
Separate enable pins for each channel allow for  
PWM dimming  
Over-temperature protection  
Other drivers with currents in the range of 20 - 30mA are  
available. The drive current is fixed, with a ±±6 tolerance  
over a VOUT range of 4 - 15V.  
8-Lead SOIC (w/Heat Slug) package  
Separate enable pins for each channel allow for PWM  
dimming, 3-step linear dimming, or individual disconnection  
of faulty LED strings.  
Applications  
LCD backlighting  
Indicator lamps  
Over-temperature protection circuitry shuts down all 3  
channelswhenthenominaldietemperaturereaches135°C.  
Normal operation resumes when the die temperature drops  
by 30°C.  
The CL320 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.

Absolute Maximum Ratings are those values beyond which damage to  
the device may occur. Functional operation under these conditions is not  
implied. Continuous operation of the device at the absolute rating level  
may affect device reliability. All voltages are referenced to device ground.
