MBI5016 contains CMOS shift registers and latch functions, converting serial input data into parallel output format. At the output stage, sixteen regulated current sources, implemented in Bipolar Junction Transistor, were designed to provide 5-90 mA constant current for driving LEDs. MBI5016 provides users with great flexibility and device performance while using MBI5016 in their LED panel system design. Users may adjust the output current of MBI5016 through an external resistor, Rext, which gives SOP24-P-300-1.00 Weight: 0.28g(typ) MBI5016CP SSOP24-P-150-0.64 users flexibility in controlling the light intensity of LEDs. MBI5016 guarantees to endure 17V at the output port, allowing users to connect more LEDs in series. The high clock frequency, 20 MHz, also satisfies the system requirement of high volume data transmission. ÓMacroblock, Inc. 2003 Floor 6-4, No. 18, Pu-Ting Rd., Hsinchu, Taiwan 30077, ROC.
