LTC3219

250mA general-purpose 9-channel LEDdrive

peculiarity

  • The multi-mode charge pump provides up to 91% efficiency
  • Slew rate-limited switching reduces conducted and radiated noise (EMI)
  • Up to 250mA total output current
  • Nine 28mA general-purpose current sources with 64 steps of linear brightness control
  • Two-wire I2CTMInterface for independent turn-on/off, brightness level, flicker, and grayscale control for each current source
  • Internal current reference
  • Configurable ENU pins for asynchronous LED turn-on/off-control
  • The low noise charge pump can operate in 1x, 1.5x, or 2x mode for optimal efficiency
  • Automatic or forced mode switching
  • An internal soft-start feature limits inrush current
  • Short circuit/thermal protection
  • 3mm x 3mm 20-pin QFN plastic package

  • description

    LTC®The 3219 is a highly integrated multi-display LED driver. The device includes a high efficiency, low noise charge pump to power nine general-purpose LED current sources. The LTC3219 requires only five small ceramic capacitors to form a complete LED supply and current controller.

    The maximum display current is set by an internal precision current reference. Independent dimming, on/off, flicker, and grayscale control of all current sources are I2C serial interface to implement. A 6-bit linear DAC can be used to adjust the brightness level of each general-purpose LED current source.

    The LTC3219 charge pump optimizes efficiency based on the voltage across the LED current source. The device powers up in 1x mode and automatically switches to boost mode when any enabled LED current source begins to enter a dropout state. The first voltage drop will convert the IC to 1.5x mode, and subsequent voltage drops will switch the LTC3219 to 2x mode. When a data register passes through I2When the C port is updated, the device is reset to 1x mode.
