Product Description
MBI5025 is designed for LED displays. As an enhancement of its predecessor, MBI5016,
MBI5025 exploits PrecisionDrive™ technology to enhance its output characteristics. 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 provides users with great flexibility and device performance while using MBI5025 in
their system design for LED display applications, e.g. LED panels. Users may adjust the output
current from 3 mA to 35 mA through an external resistor, R_ext, which gives users flexibility in
controlling the light intensity of LEDs. MBI5025 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.
