Product Description

Conditions

IOUT=25mA@VDS=0.7V

IOUT=3mA~45mA@VDS=0.7V; VDD=5.0V

With PrecisionDrive™ technology, MBI5024 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. MBI5024 contains a serial buffer and data latches

which convert serial input data into parallel output format. At MBI5024 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.

MBI5024 provides users with great flexibility and device performance while using MBI5024 in their system design

for LED display applications, e.g. LED panels. It accepts an input voltage range from 3V to 5.5V and maintains a

constant current up from 3mA to 45mA determined by an external resistor, Rext, which gives users flexibility in

controlling the light intensity of LEDs. MBI5024 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.
