Step-Down 1A Dimmable LED Driver MBI6653

 Step-Down 1A Dimmable LED Driver

简要
MBI6653 is a step-down constant-current high-brightness LED driver to provide a cost-effective design solution for interior/exterior illumination applications. It is designed to deliver constant current to light up high power LED with only 4 external components. With hysteretic PFM control scheme, MBI6653 eliminates external compensation design and makes the design simple.

    MBI5035 is a 16-channel constant current LED driver with VDS=0.2V @ IOUT=20mA, which is excellent compared to the conventional design. MBI5035 is especially designed for low power consumption LED display applications. The low knee voltage (LKV) design makes MBI5035 work at a constant output current with low VDS and still guarantees PrecisionDrive™ feature. With PrecisionDrive™, MBI5035 is designed for LED displays which require to operate at low current and match the luminous intensity of each channel. MBI5035 contains a serial buffer and data latches which convert serial input data into parallel output format. At MBI5035 output stage, sixteen regulated current ports are designed to provide uniform and constant current sinks for driving LEDs within a large range of VF variations.
     
    MBI5035 provides users with great flexibility and device performance in their low power system design for LED display applications. It accepts an input voltage range from 3.3V to 5.0V and maintains constant current up from 3mA to 40mA determined by an external resistor, Rext, which gives users flexibility in controlling the light intensity of LEDs. MBI5035 guarantees to endure maximum 17V at the output port. The high clock frequency, 25 MHz, also satisfies the system requirements of high volume data transmission.
