LTC3220/LTC3220-1  
360mA Universal  
18-Channel LED Driver  
FEATURES  
DESCRIPTION  
n
Eighteen 20mA Universal Current Sources with  
TheLTC3220/LTC3220-1arehighlyintegratedmulti-display  
LEDdrivers.Thesepartscontainahighefficiency,lownoise  
charge pump to provide power to up to eighteen universal  
LED current sources. The LTC3220/LTC3220-1 require  
only five small ceramic capacitors to form a complete  
LED power supply and current controller.  
64-Step Linear Brightness Control  
n
Independent On/Off, Brightness Level, Blinking and  
Gradation Control for Each Current Source Using

2-Wire I C Interface  
n
Low Noise Multi-Mode Charge Pump (1x, 1.5x, 2x)  
Provides Up to 91% Efficiency  
The LED currents are set by an internal precision cur-  
rent reference. Independent dimming, on/off, blinking  
and gradation control for all universal current sources  
n
Slew Limited Switching Reduces Conducted and  
Radiated Noise (EMI)  
n
Up to 360mA Total Output Current

Internal Current Reference  
are available to adjust brightness levels independently for  
each universal LED current source.

Single Reset Pin for Asynchronous Shutdown and  
Reset of All Data Registers

TheLTC3220/LTC3220-1chargepumpoptimizesefficiency  
based on the voltage across the LED current sources. The  
part powers up in 1x mode and will automatically switch  
to boost mode whenever any enabled LED current source  
begins to enter dropout. The first dropout switches the  
parts into 1.5x mode and a subsequent dropout switches  
the LTC3220/LTC3220-1 into 2x mode. The parts reset to  
Two I C Addresses Are Available (LTC3220: 0011100,  
LTC3220-1: 0011101)
