Product Description
MBI5026 is designed for LED displays. As an enhancement of its predecessor, MBI5016, MBI5026 exploits
PrecisionDrive™ technology to enhance its output characteristics. MBI5026 contains a serial buffer and data
latches which convert serial input data into parallel output format. At MBI5026 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.
MBI5026 provides users with great flexibility and device performance while using MBI5026 in their system design
for LED display applications, e.g. LED panels. Users may adjust the output current from 5 mA to 90 mA through an
external resistor, R
ext
, which gives users flexibility in controlling the light intensity of LEDs. MBI5026 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.
