MBI5016CF
Product Description
The MBI5016, utilizing the most advanced silicon
technology, is targeted for LED panel display. The
MBI5016 contains CMOS shift registers and latch
functions, converting serial input data into parallel output
format. At output stage, sixteen regulated current sources,
implemented in Bipolar Junction Transistor, were
designed to provide 5-90 mA constant current for driving
the LEDs.
The MBI5016 provides users great flexibility and device performance while using the
MBI5016 in their LED panel system design. Users may adjust the output current of the MBI5016
through an external resistor R-EXT, which gives users flexibility in controlling the light intensity
of LEDs. The MBI5016 guarantees 17V output driving capability, allowing users to connect more
LEDs in series. The high clock frequency, 20 MHz, also satisfies the system requirement of high
volume data transmission.
