The LTC®3220/LTC3220-1 are highly integrated multidisplay LED drivers. These parts contain a high efficiency, low noise 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. The LED currents are set by an intern.
n Eighteen 20mA Universal Current Sources with 64-Step Linear Brightness Control n Independent On/Off, Brightness Level, Blinking and Gradation Control for Each Current Source Using 2-Wire I2C Interface n Low Noise Multi-Mode Charge Pump (1x, 1.5x, 2x) Provides Up to 91% Efficiency n Slew Limited Switching Reduces Conducted and Radiated Noise (EMI) n Up to 360mA Total Output Current n Internal Current Reference n Single Reset Pin for Asynchronous Shutdown and Reset of All Data Registers n Two I2C Addresses Are Available (LTC3220: 0011100, LTC3220-1: 0011101) n Automatic or Forced Mode Switchin.
