ADP1655ACBZ-R7 Dettagli del prodotto

GENERAL DESCRIPTION
The ADP1655 is a very compact, highly efficient, dual white LED flash driver for high resolution camera phones, which improves picture and video quality in low light environments. The device integrates a 2 MHz synchronous inductive boost convertor, an I2C-compatible interface and a 500 mA current source. The high switching frequency enables the use of a tiny, low profile 2.2 μH power inductor, and the current source permits LED cathode grounding for thermally enhanced, low EMI and compact layouts.

FEATURES
    Ultracompact solution
        Small 2 mm × 1.5 mm 12-ball WLCSP package
        Tiny, low profile 2.2 μH power inductor
        LED current source for local LED grounding and low EMI
        Synchronous 2 MHz PWM boost convertor, no external diode
    High efficiency: 88% peak
        Reduces high levels of input battery current during flash
        Limits battery current drain in torch mode
    I2C programmable
        Currents up to 400 mA in flash mode for two LEDs
        Currents up to 500 mA in flash mode for one LED with 5% accuracy
        Currents up to 160 mA in torch mode with 10% accuracy
        Peak inductor current limit
        Flash timer
    Control
        I2C-compatible control registers
        External STROBE pin
        External direct TORCH pin
        TX_MASK input to prevent high input battery current levels
    Safety
        Thermal overload protection
        Flash timeout
        Inductor fault detection
        Output overvoltage
        Short circuit protection
        Soft start reduces inrush input current

APPLICATIONS
    Camera-enabled cellular phones and smart phones
    Digital still cameras, camcorders, and PDAs
