With PrecisionDrive™ technology, MBI5124 is designed for LED displays which require to operate at low currentand to match the luminous intensity of each channel. It provides supply voltage and accepts CMOS logic input at3.3V and 5.0V to meet the trend of low power consumption. MBI5124 contains a serial buffer and data latches whichconvert serial input data into parallel output format. At MBI5124 output stage, sixteen regulated current ports aredesigned to provide uniform and constant current sinks for driving LEDs within a large range of VF variations.Besides, MBI5124 integrates the pre-charge circuit which can relieve the ghosting.
MBI5124 provides users with great flexibility and device performance while using MBI5124 in their system design forLED display applications, e.g. LED panels. It accepts an input voltage range from 3.3V to 5V and maintains aconstant current up from 1mA to 25mA determined by an external resistor, Rext, which gives users flexibility incontrolling the light intensity of LEDs. MBI5124 guarantees to endure maximum 17V at the output port. The highclock frequency, 25 MHz, also satisfies the system requirements of high volume data transmission.
