LED driver
3 - 5.5 V, 1 - 45 mA | MBI5025 Macroblock

With PrecisionDrive™ technology, MBI5025 is designed for LED displays which require to operate at low current and to match the luminous intensity of each channel. It provides supply voltage and accepts CMOS logic input at 3.3V and 5.0V to meet the trend of low power consumption. MBI5025 contains a serial buffer and data latches which convert serial input data into parallel output format. At MBI5025 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. MBI5025 accepts an input voltage range from 3V to 5.5V and maintains a constant current up from 1mA to 45mA determined by an external resistor, Rext, which gives users flexibility in controlling the light intensity of LEDs.
