16-Channel Constant Current Sink for LED Driver
Product ID: PT6724Send Inquiry
The PT6724 is a 16-channel current sink driver for LED clusters. It contains a serial buffer and data latches which convert serial input data into parallel output format. At output stage, sixteen regulated current ports are designed to provide uniform and constant current sinks for driving LEDs. The output current is determined by an external resistor and the brightness control code, both set by users. PT6724 can used to control LEDs intensity with output enables as PWM input function.PT6724 provides users with great flexibility and performance. Users may adjust the output current from 1mA to 45mA which gives users flexibility in controlling the light intensity of LEDs. The PT6724 guarantees to endure maximum 17V at the output port.
