BCT5028
16-channel LED driver for Large Display Wall
General Description
BCT5028S/M/T/F is 16-channel constant-current driver for LED displays with 8-bit output current gain control. The output current value can also be set using an external resistor. BCT5028S/M/T/F contains a serial buffer and a 16-bit data latches, which convert serial input data into parallel output format. At BCT5028S/M/T/F output stage, sixteen regulated current ports are designed to provide constant current sinks for driving LEDs within a wide range of LED forward voltage variations. BCT5028S/M/T/F provides a clock frequency of 25MHz which satisfies the system requirements of high volume data transmission.
