Product Overview

The LTC3220EPF#PBF is a highly integrated multi-display LED Driver contains a high efficiency, low noise charge pump to provide power to up to eighteen universal LED current sources. The LTC3220 requires only five small ceramic capacitors to form a complete LED power supply and current controller. The LED currents are set by an internal precision current reference. Independent dimming, ON/OFF, blinking and gradation control for all universal current sources is achieved via the I²C serial interface. 6-bit linear DACs are available to adjust brightness levels independently for each universal LED current source. The LTC3220 charge pump optimizes efficiency 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 into 2x mode.
  • Low noise multi-mode charge pump provides up to 91% efficiency
  • Slew limited switching reduces conducted and radiated noise (EMI)
  • Internal current reference
  • Automatic or forced mode switching
  • Internal soft-start limits inrush current
  • Short-circuit/thermal protection
