    LM2755 SNVS433D – OCTOBER 2007 – REVISED APRIL 2013 LM2755 Charge Pump LED Controller with I2C-Compatible Interface in DSBGA Package
    Check for Samples: LM2755 FEATURES DESCRIPTION The LM2755 is a charge-pump-based, constant
    current LED driver capable of driving 3 LEDs with a
    total output current up to 90mA. The diode current
    waveforms of each LED can be trapezoidal with
    timing and level parameters (rise time, fall time, high
    level, low level, delay, high time, low time)
    programmed via an I2C-compatible interface. The 32
    brightness levels found on the LM2755 are
    exponentially spaced (as opposed to linearly spaced)
    to better match the response of the human eye to
    changing brightness levels. 1 2 90% Peak Efficiency
    Total solution size < 13mm2
    No Inductor Required: Only 4 Inexpensive
    Ceramic Caps
    3 Independently Controlled Constant Current
    Programmable Trapezoidal Dimming
    Waveform on Each Output
    Programmable Timing Control Via Internal
    Registers and External Clock Synchronization
    Input ...
